Proper installation and periodic maintenance determine how reliably protective relays isolate faulted equipment. You want to know whether a relay will operate under fault conditions, so our goal at DYMAX is to achieve maximum performance of your system.
 Settings can drift over time and with temperature changes, and dirt can affect the response of a relay, particularly with some of the older, induction disc units. Accordingly, periodic testing of the relays will verify that the device will operate just as expected when actual currents and/or voltages are applied and the response compares favorably with design data. The ideal relay selections and settings would be made from a coordination study.
 The DYMAX instrumentation department uses state-of-the-art testing equipment to verify and calibrate relays. We are experienced with General Electric, Westinghouse, ABB, Basler, Schweitzer, Beckwith and many other types of relays. DYMAX provides you with documentation of test values for performance and settings.
If needed, DYMAX engineers can study your system and ascertain that the settings are suitable for your application by comparing transformer capability, short circuit analysis and circuit load studies with the existing relay settings.
