Voltage Current Monitoring System is a reliable predictive maintenance tool that provides critical information to help prevent shaft current damage to seals, bearings, couplings and gears.

Voltage Eelectric Motors uses electrical energy to produce mechanical energy. The reverse process, that of using mechanical energy to produce electrical energy, accomplished by a generator or dynamo. Traction motors used on locomotives often perform both tasks if the locomotive is equipped with dynamic brakes. These motors are used in household appliances such as fans, refrigerators, washing machines, pool pumps, floor vacuums, and fan-forced ovens.

A voltage indicator is used to supply an indication signal to indicate that a voltage of a battery passes a given value. It comprises a battery terminal for connection to the battery, a reference voltage source for supplying a reference voltage and a comparator for comparing the reference voltage with a voltage on the battery terminal.
