Hot tags: PT accuracy tester, voltage transformer tester
1. The software algorithm is accurate, the accuracy of measurement data to further improve the intelligent judgment connection status, prompt connection error, wrong polarity ratio, etc..
2. The use of aluminum chassis, with good anti-interference, and to ensure the safety of the operation personnel and equipment safety in the field of high voltage test.
4. Single instrument can realize the error test of voltage transformer, no need of resonance booster device, standard voltage transformer, load box, check instrument and other equipment, greatly reducing the workload of the field calibration error.
5. The test range is wide, can test the voltage level of 6kV~800kV electromagnetic voltage transformer.
6. The test wiring, operation is simple and easy to learn, just according to the guide prompt operation can easily complete transformer calibration work greatly improve the test efficiency. Test time is short, less than 5 minutes.
