19070 Series Hipot Tester Light Ballast Application

A ballast is the circuit element that limits the electric current or provides a starting voltage, as in fluorescent lighting fixtures.In fluorescent lighting fixtures, the ballast is the transformer that converts line voltage to a lower voltage that then illuminates the lamps. The transformers MUST be tested to verify that when a consumer changes a bulb no line voltage passes to any surface where the consumer may come in contact. ■
