Secondary Current Injection Test Set Three Phase Relay Protection Tester
Can you test relays with a multimeter?
Generally, it is not recommended to measure the parameters of the secondary circuit tester with a multimeter, because the measurement range of the multimeter may not be sufficient to cover the parameter range of the secondary circuit tester, and the measurement accuracy of the multimeter may not be high enough, which may affect the accuracy of the test results.
The parameters of the secondary circuit tester include voltage, current, frequency, phase, and other values that need to be accurately measured within a certain range to ensure the stability and safety performance of the power system. Therefore, it is recommended to use dedicated secondary circuit testers for testing and calibration.
If a dedicated secondary circuit tester is not available, calibrated electronic test instruments such as digital multimeters, oscilloscopes, and others can be considered for measurement. However, before using any test instrument for measurement, it is important to carefully read the instructions for the test instrument and follow the operating procedures outlined in those instructions to avoid erroneous measurements and improper operation that could result in equipment damage or safety accidents.
Functions
1. Testing protective relays: Secondary injection testers can test protective relays by simulating fault conditions and checking the performance of the relays.
2. Simulating fault conditions: The tester can simulate a wide range of fault conditions, such as overcurrent, undervoltage, overvoltage, and phase-to-phase faults.
3. Measuring relay response times: The tester can measure the response time of protective relays to ensure that they operate within the required time limits.
4. Testing breaker control circuits: Secondary injection testers can test the control circuits of circuit breakers by simulating the opening and closing of the breakers.
5. Testing trip circuits: The tester can test the trip circuits of protective relays to ensure that they are functioning correctly.
