Need for Regular Testing

Protection Relays are called as silent sentinels of Power System

They are called upon to act only in the event of Fault/Abnormal Condition and are silent during normal operation.

Thus maloperation of these relays during abnormal conditions result in heavy damage and loss. To avoid this it is necessary to ensure fail safe measures are working at all times. For this, it is prudent to test their healthiness by regular inspection and testing.

EPROSYS with their trained personnel and with state of art testing equipment have full capabilities to provide Testing and Calibration services to assure your protection system is properly calibrated and is in good working conditions.

EPROSYS has facility to do Primary and Secondary Injection Testing.

EPROSYS with their three Stage testing process and Documented Test Procedures ensure proper and correct testing at all times employing minimum shutdown time.

EPROSYS has capabilities to test –

• ANY TYPE of Relay ranging from Electromechanical to Numerical including configuration of Numerical Relays.
• ANY MAKE OF Relay viz: AREVA, ALSTOM, SCHNEIDER, ABB, SIEMENS, GEMultilin, C&S, Easun Reyrolle, ASHIDA, ALIND, ANDREW YULE, JVS, SCHLUMBEGER etc.
• ANY Protection Application – Feeder, Tranformer, Generator, Motor, Bus Bar etc.

Our site team recognizing the problem of contamination by dust and moisture in our Tropical climate lays emphasis on thorough cleaning of relays and its contacts using non-destructive methods during testing.

We test and Calibrate Relays over the entire range and not limited to testing at Settings only, unlike others ensuring relay functions well over entire range whenever need arises.

WITH OUR EXPERIENCE WE ADD VALUE through pertinent recommendations on the condition of the relays and correct settings.

Testing of Other Electrical Equipment & Systems.

EPROSYS now extends its services to test all the Substation, Switchgear, Control Panels.

• We now test all the Substation Equipment including Distribution lines, Insulators, Current transformer, Potential transformer, Switchgear (Circuit Breakers, Switchesetc) Transformers by Primary Injection, Secondary Injection and Thermographic scanning.
• We test Meters, Tranducers, Thermal Overload Relays With our domain knowledge and expertise, we are regularly testing verticals in Control and Relay Panels.
• Pre Commissioning & Commissioning Services
• We have the expertise to test all types of panels apart of Control and Relay panels Viz Synchronising Panels, MCC, PCC, Logic panels and Battery Charger Panels testing of all types of Panels
• We have expertise to test in both Open Cast and Underground Mining Industry following all safety norms and DGMS requirements regularly proving services in Singareni collieries and NMDC etc.
