The high and low voltage current transformer ratio tester developed by our company is a new type of electricity inspection device for high-voltage metering users. It can detect the ratio and polarity of current transformers used in metering devices at 35KV and below without power interruption or line modification, thereby effectively preventing high-voltage metering users from replacing high and low voltage current transformers or their nameplates, or changing the polarity of secondary lines to reduce metering and steal electricity. This instrument is easy to use, portable, and has a high safety factor, making it an indispensable detection tool for electricity inspection personnel.

According to user requirements, the high-voltage clamp meter can be equipped with a liquid crystal display and used independently as a device for measuring current in high-voltage lines.
