Transformer testers can accurately measure various performance indicators of transformers, providing reliable guarantees for the safe and stable operation of transformers.
Improving the service life of transformers
Transformer testers can monitor the operating status and performance of transformers, detect and solve problems in a timely manner, and thus extend the service life of transformers.
Improving the maintenance efficiency of transformers
Transformer testers can quickly and accurately measure various parameters of transformers, providing reliable data support for transformer maintenance and repair, thereby improving maintenance efficiency.
Reduce the failure rate of transformers
Transformer testers can promptly detect and solve transformer problems, thereby reducing the failure rate of transformers and minimizing losses caused by faults.
Types of Transformer Test Instrument
Insulation oil tester
Used to detect the quality indicators of insulating oil, such as dielectric strength, acid value, etc., and to monitor the internal condition of the transformer in a timely manner.
Transformer ratio tester
This instrument can accurately measure the transformer ratio, quickly detect electrical faults and locate them.
Partial discharge detector
It can detect partial discharge phenomena in the insulation system and timely warn of potential faults.
Thermometer and hygrometer
Used to monitor the working environment of the transformer to ensure that the environmental parameters meet the requirements.
DC resistance tester
Used to test the DC resistance of the winding, effectively detecting faults such as poor contact and short circuit.
