If the protective relays are not monitoring or measuring properly, they can cause false tripping or non-tripping. Since these devices operate during abnormal conditions on the power system, the only way to ensure correct operation is by a comprehensive inspection, maintenance, tests and calibration programs.

Protective relays are decision-making elements in the protection scheme for electrical power systems. They monitor circuit conditions and initiate protective action when an undesired condition is detected.

We facilitate a strong maintenance and test program which will keep your protective relays in a high state of readiness ensuring they respond properly to normal and abnormal conditions and help you avoid equipment damage, prolonged downtime and employee injuries.

We follow IEC 60255 guidelines, which specifies common requirements and rules applicable to measuring relays and protection equipment. This includes any combination of devices to form schemes for power system protection such as control, monitoring and process interface equipment in order to obtain uniformity of requirements and tests.
