A protective relay is designed to calculate operating conditions on an electrical circuit and trip circuit breakers when a fault is detected. Relays should always be kept in proper working condition to ensure electrical safety and reduce possible damage to other devices.
Relay test sets are used to assess relays by applying sufficient current to simulate specific conditions and check if the relay will operate as it was meant to do.
One of the most popular test sets used in the industry is Doble F6150 Relay Testing System. The Doble F6150 offers flexibility, high power, and a well-built software package that can run complete simulation tests on relays as well as protection schemes. With a 3-phase relay system that supports standard test templates and automated procedures the Doble F6150 assures that test methods are consistent.
The Doble F6150 control panel software is easily customizable and has options for manual testing, along with a flexible configuration that supports 6 sources rated 150VA at currents of 0-30A.
Able to test any relay between 0.5A and 180A at high power, the Doble F6150 is capable of tesing everything from a small and simple ground/earth fault relay to a modern and completely multifunctional microprocessor protection scheme, with no need for any additional instruments. The F6150 from Doble can even be used via GPS technology and units can be remotely synchronized.
