The Relay Test Equipment we have available for hire is the following:
Programma SVERKER 760 Relay Test Unit
The SVERKER 760 features many functions that make relay testing more efficient. To cite one example, its powerful measurement section can display (in addition to time, voltage and current) Z, R, X, S, P, Q, phase angle and cos ϕ. The voltmeter can also be used as a 2nd ammeter (when testing differential relays for example). All values are presented on a single easy-to-read display. Thanks to its built-in variable voltage source (amplitude and phase angle), SVERKER 760 can also test directional protective equipment efficiently. Automatic reclosing devices can also be tested – just as easily. Fine regulation of current is easy thanks to the built-in set of resistors.

Programma B10E AC/DC Voltage Power Supply
A variable DC voltage is needed to test a circuit breaker. Substation batteries should not be used since this entails considerable risk for testing personnel, testing equipment and also for the equipment being tested. The best way to ascertain whether or not solenoids and protective mechanisms are sluggish or working properly is to perform a test at minimum tripping voltage. The minimum trip voltage test is described in international and national standards such as IEC 62271-100, ANSI C37.09 etc. B10E can be used to test breaker coils in this manner. It provides a ripple-free variable DC voltage that can easily accommodate a high, variable load. Since there is a separate output for supplying spring charging motors, the B10E is ideal for testing circuit breakers where auxiliary voltage is not connected or available.
