WebThe partial discharge measurement made by PD testers, using the surge test as the driver, is the voltage of the PD spikes. This voltage is proportional to the amount of discharge and measured in mV. The range measured is typically from a few mV to a few volts. A charge or discharge is measured in coulombs. 1 coulomb = 1A for 1 second. WebTypically, there are two classes of motor testing; Online dynamic testing provides the data for power quality and specifies under which conditions you should operate a motor. With this type of testing, you should collect the readings on power condition, voltage level and imbalance, load and torque from a moving motor.
