The Megger MRCT Relay and Current Transformer Tester is a portable unit used to perform demagnetization, ratio, saturation, winding resistance, polarity, phase deviation, and insulation tests on current transformers, and automatically calculates ratio errors, saturation curves, and knee points.
Upgraded to include additional functionality, further enhancing instrument transformer testing capabilities including:READ MORE >>
High amp power is what’s needed in a relay test set for proper testing of protection relays. The Omicron CMC 356 Universal Relay Test Set and Commissioning Tool can handle high burden electro mechanics on transformers reliably, and its digital technology provides an unmatched dependability even in small amp testing situations.READ MORE >>
The testing of high impedance electromechanical relays is a challenge for any test instrument. This is especially true if an over-current electromechanical relay is being used to detect ground or earth faults, one of the most critical and sensitive protections in the system. The ground over-current relays are relied on the most when everything else fails to detect a high resistance fault in the system, therefore it is vital to ensure that the ground over current relays are working correctly.READ MORE >>
Conventional steady-state tests sets are only capable of testing each component of the system individually, therefore it becomes very difficult to predict the behavior of the entire system when subjected to true power system events. This results in performance uncertainties and could be the cause of misoperations.READ MORE >>
Performing diagnostic tests on relays usually requires accurate test sets to ensure their safety. A false "pass" result can lead to serious problems in your electrical system. It is wise to rent a high quality test set to ensure reliable test results.READ MORE >>
For primary injection testing of current transformers, VTs or differing types of relays, the Omicron CMC 356 Universal Relay Test Set and Commissioning Tool is the high powered, versatile solution.READ MORE >>
Protective relays are designed to be responsive to an abnormal current or power flow. They are used in combination with medium voltage circuit breaker (above 600 volts) to sense abnormalities and isolate disturbances, with minimum disruption to the electrical system, preventing damage to the equipment.READ MORE >>
The Megger SMRT410 Multi-phase Relay Tester has the “smart” combination of high compliance voltage and high current output to test all electromechanical, solid-state and microprocessor-based overcurrent relays, including; voltage controlled, voltage restraint and high impedance directional ground overcurrent.
The Megger SMRT410 Multi-phase Relay Tester provides a complete multi-phase test system for commissioning of protection systems. With up to 4 voltage channels and 6 high current channels, the SMRT410 meets every testing need.READ MORE >>
The Doble F6150 Relay Testing System can be used to measure the majority of relays.
And while it is capable of measuring high-burden electromagnetic earth fault relay, it is also sophisticated enough to complete advanced multi-functional numerical microprocessor protection schemes. It can do that without any additional devices, making the Doble F6150 Relay Testing System very popular for relay testing.READ MORE >>
