Greenlee Tools
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.

Vanguard Instruments Company, Inc.
The ATRT-01 S3 is Vanguard’s fourth generation, micro-processor based, single phase, automatic transformer turns-ratio tester. The ATRT-01 S3 uses the IEEE C57.12.90 measuring method to determine the transformer turns-ratio. The transformer turns-ratio is determined by precisely measuring the voltages across the unloaded transformer windings. The ATRT-01 S3’s measuring circuitry self adjusts before each measurement to ensure turns-ratio accuracy. Two selectable test voltages, 4Vac and 40Vac, offer flexibility in testing different types of transformers.
