Test objects

All kinds of power system relays, such as overcurrent relays, overvoltage relays, undervoltage relays, differential relays, zero-sequence relays, etc., as well as mechanical meters and electronic meters (related to the calibration function of electric energy meters). When it comes to the SF6 gas sealing detection of high-voltage switchgear, the relevant equipment can be tested.

Test items

• Relay action characteristic test: Detect the relay's action time, return time, action value, return value and other parameters to evaluate the accuracy and reliability of its action.
• Electrical parameter test: Including the output and measurement of electrical parameters such as voltage, current, frequency, and phase angle to verify the performance of the relay under different electrical conditions.
• Harmonic test: Inject up to 60 harmonics to test the operation of the relay in a harmonic environment.
• Synchronous test: Use the GPS synchronization function to test the consistency of the relay's action under synchronous conditions.
• Fault simulation test: Through functions such as the switch-on fault test (SOTF), simulate power system faults and detect the protection function of the relay.
• SF6 gas tightness test: For high-voltage switchgear, according to IEC 62271-203 standard, the annual leakage rate of SF6 gas and other tightness parameters are tested.
