1, high voltage test transformer: used to generate high voltage to carry out the voltage test of the equipment.
2, high voltage switch tester: used to test the electrical and mechanical properties of the switch, including the switch action time, speed, synchronization and so on.
3, partial discharge detector: used to detect the partial discharge phenomenon inside the equipment to evaluate the insulation status of the equipment.
4, dielectric loss tester: used to measure the dielectric loss of insulating materials, so as to judge its insulation performance. 5, arrester tester: used to test the performance of the arrester, including leakage current, operating voltage, etc. 6, cable fault tester: used to detect the fault point in the cable, such as broken, short circuit, etc.
7, capacitance and inductance tester: used to measure the electrical parameters of capacitance and inductance to judge its working state. 8. Instrument transformer tester: used to test the performance parameters of current transformer and voltage transformer.
9, oil chromatography analyzer: used to analyze the gas composition in the transformer oil to judge the operating status of the equipment. 10, DC resistance tester: used to measure the DC resistance of transformers, motors and other equipment to evaluate the connection status of their windings.
In addition to the above equipment, the 110kV substation may also be equipped with other auxiliary equipment, such as temperature and humidity meters, vibration monitors, etc., to comprehensively monitor the operating environment of the substation.
