The VPIS-R1 high-voltage live display device is used to provide information on the voltage status of the main circuit of the high-voltage electrical equipment being monitored to the operation and inspection personnel, which can prevent them from accidentally entering the live interval. At the same time, the device itself has a nuclear phase function.

The product complies with the requirements of IEC 61958 international standard and DL/T538-2006 power industry standard.
