A continuity tester is a simple electrical device with a metal probe, a tester light, and a wire with a clip at one end. All it does it test for continuity or a complete electrical circuit. A circuit that is "open" is broken and has no continuity. A circuit that is "closed" has continuity. A light switch opens and closes a lighting circuit. Transformer Testing Power transformers are critical and expensive assets that require thorough inspections and testing throughout their operational life. Integral Power’s transformer testing can reveal a range of defects and deficiencies that could compromise the reliability of your system and/or the safety of your personnel. Transformers are ratiometric, so the relative voltages will be the same using your low voltage AC test vs. when you identify the intended primary winding and apply 115VAC to it. Doing this, you should have a good sense as to what windings are present that the relative turns ratio between each.

The MIT200 series of insulation and continuity testers are ideal for testing transformers, motors, generators, switchgear, panel building, domestic appliances, power tools etc., as well as fixed electrical wiring systems. Their small size and light weight make them ideal for those engineers that need to carry them for extended periods.
Transformer test equipment. Making a well-informed choice in equipment for transformer testing is an important step towards ultimately improving transformer life management decisions. The test and assessment of transformers is a complicated task. Insulation resistance test for cable using megger is a continuity test, where the power of the circuit is off. For example, if the cable is of the capacity of 5Amps, we can send current less than or equal to 5Amps and not more than that. If we send more than 5Amps this may cause the failure of the cable.
The 3312 Telecom Transformer Test System is a precision test system, designed for telecom transformer production line or incoming/ outgoing inspection in quality control process, with high stability and high reliability.

The OCV is usually about 5 to 10% higher than the nameplate voltage. If no voltage is read, turn off the power, disconnect the transformer, and do a continuity test of the transformer’s primary and secondary. If there is a short in the secondary, usually the fuse will open, or the winding itself may be found open. CONTINUITY TEST 1.
