Series of single channel ohmmeters capable of measuring motor winding resistance while the motor is running. With a sophisticated decoupling system and a direct current generator, which does not disrupt the system’s operation while the direct voltage is simultaneously read on the winding, with a measurement precision of 0.3%. To carry out the measurement, the power supply voltage of the motor must be sinusoidal. Measurement with PMW power supply from the inverter is not permitted. The ohmmeter series are available in table, rack, box and board versions.
Series of dual channel ohmmeters capable of measuring motor winding resistance while the motor is running. With a sophisticated decoupling system and a direct current generator, which does not disrupt the system’s operation while the direct voltage is simultaneously read on the winding, with a measurement precision of 0.3%. To carry out the measurement, the power supply voltage of the motor must be sinusoidal. Measurement with PMW power supply from the inverter is not permitted. The ohmmeter series are available in table, rack, box and board versions.
Two channel device to measure the coils winding resistances of an inverter driven motor (PWM) in operation with applied voltage.
