High voltage motor insulation monitoring instrument ZX-10H

The high-voltage insulation monitoring instrument adopts the direct current high-voltage injection method to measure the insulation of cables or motor windings, with a test voltage of DC2500v. The instrument is interlocked with the circuit contactor or circuit breaker auxiliary contact to achieve the separation of the insulation monitoring instrument from the power grid when the motor circuit is powered on. When the line is powered off, the insulation monitoring instrument automatically starts to monitor the insulation of the line. Although the insulation monitoring instrument only monitors after the busbar is powered off, considering its direct connection with the high-voltage busbar, the insulation monitoring instrument is also equipped with a coupler for protecting the line and the insulation monitoring instrument host.
