Product introduction:
YNY - Ⅳ suit is an insulation monitoring suit. The instrument is interlocked with the circuit contactor or the auxiliary contact of the circuit breaker to realize the separation of the insulation monitor from the power grid when the motor circuit is powered on. When the line is powered off, the insulation monitor automatically starts to monitor the insulation of the line. Although the insulation monitor only monitors after the bus is powered off, considering that it is directly connected to the high voltage bus, the insulation monitor is also equipped with a coupler, It is used to protect the line and insulation monitor host
