Our products include a microprocessor based current transformer test set that tests current transformers and provides a complete set of tools for commissioning of CT secondary and relay circuits. We offer a Universal Resistance Meter that measures circuit breaker contact resistance and the resistance of transformer windings. The Lake Digital catalog includes an economical 10 AMP contact resistance meter, a transformer turns ratio meter and a frequency relay test set.
Battery power is available as an option on our transformer ratio and contact resistance meters.
This unit offers 6000 AMPS short circuit output for testing of low voltage ground fault protection and circuit breakers up to approximately 600 Amperes. This instrument will offer several features not found in units currently offered. The instrument precisely measures the output circuit phase angle during test of the time overcurrent element. This allows very precise triggering of the control SCR during initiation of instantaneous element tests, virtually eliminating DC offset error. Save time and use less equipment.
