A tester for testing a transformer is provided. The tester comprises a primary voltmeter and a plurality of secondary voltmeters. The tester may also comprise an ammeter in series with a voltage source configured to apply voltage to the transformer. The primary voltmeter is configured to measure voltage induced across a primary winding of the transformer, while the secondary voltmeters may simultaneously measure voltage outputs at secondary windings of the transformer. The tester is configured to calculate ratios, saturation curves, and knee points for multiple winding combinations based on the measurements simultaneously obtained by the ammeter and the primary and secondary voltmeters.

Concurrent transformer test system and method

A programmable system for testing relays and controlling systems is provided. In one embodiment the present disclosure provides a programmable device capable of, for example, testing relays. The device includes a signal generator for generating signals to test relays. The device includes a memory location, and a first program stored in the memory location. The first program supports relay testing. The device includes a versioned program to support relay testing, and a processor in communication with the signal generator and the memory location. The device also includes a routine that is operable by the processor to install a versioned program in the memory location replacing the first program.

Relay testing system and method

A system for testing a relay is provided. The system includes a plurality of signal generators to generate signals to test relays. The system includes a controller to provide at least some inputs for use by at least one of the signal generators to generate the signals. The system also includes a hand-held controller in communication with the controller. The hand-held controller is operable to receive and display relay test information for a user. The hand-held controller is operable to transmit one or more control inputs for testing the relay.
