10kV Potential Transformer
10kV Potential Transformer (PT or VT) is a key device used for voltage measurement, energy metering, relay protection and system monitoring in power systems. Its function is to convert the voltage on the high voltage side (10kV) into a safe voltage on the low voltage side (standard value such as 100V or 100/V) for use by instruments, protection devices and control systems.
We can also provide current transformer and transformer ,welcome you inquiry .
