Low voltage testing is able to catch errors such as shorts and opens by applying current to a wire and measuring the voltage. The wire will have a current affected by several factors including resistance and components. If the wire is connected correctly, the test will read low resistance. That means current is flowing through the wire as expected and reaching the required connections. If the tester reads high resistance it means something is impeding the current from reaching its destination. This could be caused by a number of causes.

HVSCM -
Test Electronics
Designed to be used with the Model HVST High Voltage Surge tester. The Surge Current Monitor allows simultaneously surge testing 20 units. The Surge Current Monitor monitors the current going through each unit under test at the time of the surge. If a unit under test breaks down or leaks, the Surge Current Monitor will identify the bad unit by lighting the corresponding LED. The most important features of the surge tester are its ability to test the entire winding insulation system. A high voltage surge generates turn to turn, coil to coil, and phase to phase voltage stress, as well as ground insulation stress. When used as a dielectric test, accurate voltage readings are essential. The HV Surge Tester monitors the voltage directly across the winding under test. In production testing we expect that most of the time the devices will pass. In the event that one should fail, the failed device would be removed and then all the parts would have ot undergo another surge test. Since most devices pass most of the time, simultaneous surge testing can be a real time saver.
