Surge, Hipot & Megger Testing of Windings
The
technology of testing windings has dramatically improved in recent
years. 3E has proven test procedures for three phase and DC motors,
transformers and other apparatus. Windings can be dialectically tested
over potential too. This service is available both in-shop and in the
field.
Surge comparison testers, meggers and hipots are also available.
When considering rewinding of an AC stator or rotor, iron core testing is needed to insure a particular motor is a good candidate for repair. The iron core is the heart of the electric motor and must be in good shape to retain original efficiency. This instrument excites and meters the iron core to determine core condition while at the same time testing the insulation between the laminations.
Rotors are tested using several methods to insure the integrity of the circuit.
Ultra Sonic testing is used to confirm the integrity of shaft material to insure a quality repair.
