Product introduction:
The QB500 insulation monitor uses the DC injection method to measure the insulation of the cable or motor winding, and the test voltage is DC500V. If the corresponding line in the equipment is enabled, the instrument and the circuit contactor or the auxiliary contact of the circuit breaker are interlocked and controlled to realize the separation of the insulation monitor from the power grid when the motor circuit is powered on, and the insulation monitor automatically starts to monitor the insulation of the line when the line is powered off, This instrument can measure three different motors. This product mainly replaces the megohmmeter to realize the automation of measuring the line insulation resistance (the electrical insulation ability of the line to resist DC current)
