Page 3 of 15 Standard Work Practice SP0518 Ver 2 Ergon Energy Corporation Limited ABN 50 087 646 062 Ergon Energy Queensland Pty Ltd ABN 11 121 177 802 return the relay scheme to service in an acceptable standard. 5.1.4 Definitions Installs or replaces relays and associated wiring. Perform functional trip testing on power plant generating equipment. Perform functional trip testing on substation equipment schemes. Interprets and coordinates event reports, SER data, and phase diagrams for system distribuances. Perform functional trip testing breaker failure trip schemes.Remote Testing. Maintenance testing in cases such as relay mal-operation requires IED testing before putting it back in operation. In typical cases, this requires sending a testing crew to the substation to perform the tests-a time consuming and expensive process.
In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected.: 4 The first protective relays were electromagnetic devices, relying on coils operating on moving parts to provide detection of abnormal operating conditions such as over-current, over-voltage, reverse power flow, over-frequency, and under-frequency.Protective Relay Test Sets Switchgear, or relay testers, are ideal for testing Single, 3, 4 and 6 Phase protection relay systems. Commissioning tools compliant for IEC 61850 environments, high burden electromechanical relays, GPS and IRIG-B can be completed by all-in-one test sets.Protective relay and protection system commissioning. Commissioning engineers often work under difficult time constraints. The availability of equipment is essential for adhering to these time schedules. Time-saving test automation for standard test procedures is also a must for meeting the deadlines of a time sensitive environment.

All parts of the COMBIFLEX relay and the overall system can be accessed for testing. COMBITEST also means additional personnel safety during testing. In a test it is possible to inject signals to the isolated relay in order to observe its performance and operation limits.
The ANSI device number is 50 for an IOC relay or a DTOC relay. In a typical application, the over current relay is connected to a current transformer and calibrated to operate at or above a specific current level. When the relay operates, one or more contacts will operate and energize to trip a circuit breaker.
Electrical transmission, distribution and switching substations generally have switching, protection and control equipment and one or more transformers.Our electrical substation maintenance course focuses on maintenance and testing of switchgear, circuit breakers, batteries and protective relays.Inspect, test, repair, or maintain electrical equipment in generating stations, substations, and in-service relays.
