Performance parameters
Release characteristics: The thermal magnetic release method combines the advantages of thermal release and electromagnetic release. Thermal trip is mainly aimed at overload situations.

Document purpose: To introduce the differential protection setting calculation of SPAD 346 C3 protection relay module SPCD 3D53, which is applicable to two winding power transformers and involves differential protection of three winding power transformers, motors, generators, etc., including setting suggestions and discussion of intermediate current transformer (CT) requirements.
Protection principle: By comparing the phase currents on both sides of the protected object, when the differential current of a certain phase current exceeds the starting value of the stable action characteristic or the instantaneous protection stage value, the relay sends an action signal, which has the characteristics of fast action speed, high stability of faults outside the area, and high sensitivity to faults inside the area. CT selection and relay setting should be cautious.
Two winding power transformer protection
（1） Vector Group Matching (SGF1)
By using SGF1/1… 8 switches, the vector groups of power transformers are numerically matched on the high voltage (HV) and low voltage (LV) sides. Based on the phase shift and delta connection inside the relay, there is no need for intermediate CT, and the zero sequence component in the phase current can be automatically eliminated. Different vector groups correspond to different switch positions and check sums.
（2） CT ratio correction (I ₁/In, I ₂/In)
When the CT secondary current is different from the rated current under the rated load of the power transformer, the CT ratio on both sides of the transformer needs to be corrected. Calculate the rated load of the power transformer firstI nT=S n/(3 × U n), then calculate the transformation ratio correction settings I 1/In=I nT/I p (HV side) and I 2/In=I T/I p (LV side), where I p Rated primary current for CT, and the rated input current (1A or 5A) on the HV and LV sides of the relay can be different, using 1A secondary current can improve CT performance.
（3） Startup ratio (S)
Due to the inaccuracy of CT and changes in the position of the tap changer, an increase in load current will cause differential current to increase by the same percentage. The setting of the start-up ratio (S) affects the slope of the relay action characteristics between the first (fixed 0.5 × In) and second turning point (set I 2tp), which is calculated as the sum of CT accuracy on both sides, tap changer adjustment range, relay action accuracy (4%), and required margin (usually 5%).
（4） Basic Startup Settings (P/In)
The basic setting (P) defines the minimum sensitivity of protection, taking into account the no-load current of power transformers, which is generally calculated asP=0.5 × S+P, where P ‘represents the no-load loss of the transformer at maximum voltage, usually used when the actual value is unknown
P ′=10%。
（5） Second turning point (I ₂ tp/In)
The second turning point defines the point at which the influence of the activation ratio S in the action characteristics ends and the slope begins at 100%. Its setting needs to balance stability and sensitivity. In power transformer protection applications, the range of 1.5-2 is usually selected, with 1.5 being more stable for out of zone faults and 2.0 being more sensitive for in zone faults.
（6） Second harmonic blocking (Id2f/Id1f>)
The excitation inrush current of power transformers during excitation contains a large amount of second harmonic. Differential protection is locked by detecting the content of second harmonic (low setting stage). The recommended setting for second harmonic locking in power transformer protection is 15%, which can be enabled by setting the switch SGF2/1=1, and the setting can be reduced to 10% during the first excitation.
（7） Instantaneous differential current stage (Id/In>>)
It is recommended to use it together with the low setting stage to provide faster protection in case of severe faults, and is not subject to harmonic blocking. Its setting needs to be high enough to prevent the differential relay module from tripping when the transformer is excited, usually 6-10.
（8） Fifth harmonic blocking and unlocking (Id5f/Id1f>, Id5f/Id1f>>)
Used to lock the relay action when there is a sudden voltage rise (or frequency drop), based on the fifth harmonic component of the transformer excitation current to monitor overexcitation. Due to the need to know the magnetization characteristics of the transformer, it is usually not enabled, that is, SGF2/3 and SGF2/4 are set to 0.
（9） Interference recorder
The internal interference recording function of the relay module is a powerful tool for analyzing the causes of transformer inrush current and tripping. The factory default settings are used during normal operation, and the serial communication parameters V241 and V245 need to be changed during inrush current research.
Three winding power transformer protection
The SPAD 346 C relay can be used for three winding transformers or two winding transformers with two output feeders. On the dual feeder side of the transformer, the two CT currents of each phase must be summed through parallel connections, usually requiring an intermediate CT to handle vector group and/or ratio mismatches, and at least 75% of the short-circuit power should be fed from the transformer side with only one connection to the relay, otherwise it may cause unstable protection.
Motor and generator protection
The calculation process for setting up differential protection applications for motors or generators is very similar to that of power transformers, but the vector group should be set to Yy0. The starting ratio (S) is calculated as the sum of the CT accuracy on both sides, the relay action accuracy (4%), and the required margin (usually 2.5-5%). The second turning point (I ₂ tp/In) may cause CT saturation due to current during motor start-up, with a typical setting value of 1.0. The generator is usually between 1.0-1.5, and the motor and generator usually do not require second or fifth harmonic blocking.
Combination protection of motor and autotransformer
The differential relay measures the phase current on both sides of the protected object, and the protection area includes the autotransformer and motor. The current between all autotransformer/motor combinations and the network must be measured, and its setting is the same as that of ordinary motor protection applications. The autotransformer will have a typical starting sequence during the motor starting process, from power supply to acting as a parallel reactor and then to bypass.
Variable frequency motor and its power transformer protection
SPAD 346 C can only be used to protect power transformers that supply power to frequency converters, and is not suitable for protecting power transformers or motors powered by frequency converters, as the fundamental frequency component in the relay is numerically filtered through a Fourier filter and is not suitable for measuring the output of frequency converters.
Short overhead or cable protection
SPAD 346 C can be used for differential protection of overhead or cable lines. When the distance between measurement points is long, an intermediate CT may be required to reduce CT load. Using 1A secondary current can reduce CT load, and the actual accuracy limit factor (Fa) of CT can be calculated to ensure compliance with requirements.
Summary
This guide describes how to select and calculate differential protection settings for SPAD 346 C protection relays, introduces the working principle and setting effect of relays, and presents the calculation process through examples. It also describes protection application examples for three winding power transformers, motors, and generators, discusses the applicability of SPAD 346 C relays in frequency converter applications, and finally describes differential protection for short overhead or cable lines through examples of calculating the actual accuracy limit factor of intermediate CT.
Function: Convert high current in power transmission and distribution systems into low current for use in low-voltage measurement and protection equipment. The secondary current is usually 1A or 5A, connected in series, and the secondary winding is mainly connected to an ammeter and protection relay.
Principle: Through electromagnetic induction, the secondary current is proportional to the primary current, and the conversion ratio K=I ₚᵣ/I ₛᵣ=N ₂/N ₁, where I ₚᵣ is the primary current, I ₛᵣ is the secondary current, N ₁ and N ₂ are the turns of the primary and secondary windings, respectively. The secondary current I ₛᵣ=I ₚᵣ × N ₁/N ₂. It can have one or more secondary windings, each with an independent magnetic circuit, used for different purposes such as metering or protection.
Key parameter
Rated primary current (I ₚₑ): The primary current value based on the performance of the transformer, which needs to be equal to or higher than the highest primary current of the system. The standard value is in accordance with IEC regulations, such as 10, 12.5, and their decimal multiples. It can also be produced in any proportion according to the protocol, usually with a 120% extended current range to avoid high temperature rise during installation.
Frequency: It can be set as 50Hz or 60Hz, or a combination of 50/60Hz, and 16 ⅔ Hz is also possible, depending on the network of each country.
Equipment maximum voltage (U ₘ): The insulation level should be set to be equal to or higher than the system maximum voltage U ₛᵧₛ (except for cable current transformers, whose insulation is provided by the application), with standardized values, such as 3.6kV corresponding to system voltage up to 3.3kV, etc.
Insulation level: Based on the U ₘ value, such as IEC insulation level 12/28/75kV, it represents the highest voltage, power frequency withstand voltage (effective value), and lightning impulse withstand voltage (peak value) of the equipment, respectively.
Accuracy level: divided into measurement class (0.2, 0.2S, 0.5, 0.5S, 1, 3) and protection class (5P, 10P, PX, TPX, TPY, TPZ), different levels are suitable for different purposes such as tariff measurement, laboratory measurement, protection, etc. The chart shows the current ratio error limit of commonly used measurement classes.
Secondary current and number of windings: The secondary current is 1A or 5A, and the number of windings depends on the size of the body. For example, the maximum 36kV TPU 7x.6x can have up to 8 iron cores.
System primary current (I ₛᵧₛ): The system current for installing transformers needs to be equal to I ₚᵣ, and different applications have different calculation methods. For example, the transformer feeder I ₛᵧₛ=S/(√ 3 × U ₛᵧₛ), the capacitor feeder I ₛᵧ=1.3 × Q/(√ 3 × U ₛᵧₛ), where S is the apparent power (kV). A), U ₛᵧₛ is the system voltage (kV), and Q is the reactive power of the capacitor (kVar).
Rated short-time thermal current (I ₜₕₙ): The maximum primary current that a transformer can withstand for a specified short period of time without causing harmful effects. The standard values are 2, 4kA, etc., and the duration standard is 1 second, or possibly 3 seconds. The rated dynamic current I dyn is 2.5 times I ₜₕ at 50Hz.
Extended current rating (EXT): The range of current increase that a current transformer can measure at an accuracy level, such as 120%.
Maximum continuous thermal current (I ₜₕ): The maximum continuous thermal current that the current transformer can still operate but is not at the accuracy level.
Accuracy Limiting Factor (ALF): Used for protection purposes, it defines the multiple of primary current that the error must meet. For example, 5P20 represents a composite error of ≤ 5%, and the error limit from 100% primary current to 20 times primary current must be met. ALF is related to the load, and unexpected increases in load can cause ALF to decrease. The actual load required for the secondary iron core, secondary circuit, and connecting equipment needs to be calculated. Different instrument loads vary, such as 0.5-4VA for ammeters, and cable losses need to be compensated.
Safety factor (FS): Used for measurement purposes, it protects all devices connected on the secondary side by setting iron core saturation to avoid secondary high current transmission during faults. For example, FS5 indicates an error of ≥ 10% under rated load at 5 times the rated primary current.
Environmental temperature and insulation level: Environmental temperature is divided into three categories according to IEC: -5/40 ° C, -25/40 ° C, and -40/40 ° C. The insulation level of ABB products corresponds to Class E, which means the maximum temperature rise of all active components is about 75K.

Working principle
The ABB ARCOL 0346 industrial control module first receives various signals from external devices such as sensors and buttons through input interfaces during operation. After entering the module, these signals will first go through preprocessing steps such as filtering and amplification to convert them into digital signals that the module can recognize and process, and then be sent to the central processing unit. The processor performs logical operations, data processing, and analysis on input signals based on pre written and stored control programs within the module, and then generates corresponding control instructions according to established control strategies. These instructions are sent through output interfaces to corresponding actuators, such as motor drivers, solenoid valves, etc., to control the equipment to perform corresponding actions and achieve precise control of industrial production processes.
