We have single phase and 3 phase relay testers as well as Primary current Injection and Secondary Current Injection testing, PCITS, SCITS, Phase angle meters and digital timers. CTs are the communication points between the various assets in the substation and the relays so, if taking something offline in order to test the CTs, it is beneficial to have the ability to perform some standard relay tests, as needed. Service. When these two digital twins can interoperate, the highly specialized branch of the electrotechnical community, the protection of traditional substations. 90 and IEEE C37. The SVERKER 650 single-phase relay test set has been designed to incorporate the benefits gleaned from many years of experience in field relay testing Skip to main Megger’s SVERKER 650 offers secondary relay testing and primary injection for electrical distribution substations, renewable power generation stations, This has made it indispensable for protective relay testing, whether conducted using a portable relay test set, digital relay testing equipment, or advanced relay test units. MVAJ25 - Trip Relay. Aspects of protection relay 12. Additional PPE Required Nil. Virtually all types of single-phase protection can be tested. Landis+Gyr Meter Software. Home; We are involved in 400 KV to 11 KV Substations and Power Plant Erection, testing and Commissioning including Power Transformers, Switchgears, relay panel testing & commissioning, control panel testing, instrumentation and facilities of management services to meet specific client requirements. Typically responds within 1 day. Relay testing is performed to ensure the protection system functions as intended. CR0333SE V19a 2020. Commissioning Procedures Configurations Megger’s advanced relay testing software is designed to simplify the complex task of relay testing. Note down the drop off Additionally, the testing requirements for digital substations constructed in accordance with the IEC 61850 standard differ from those of conventional substations. 1 Application testing Testing of a relay to ensure it meets Ergon Energy requirements before implementation into the Ergon Energy network. Literature. The RTMS Relay Test Management Software, is the culmination of decades of automatic relay testing experience. To test such relay schemes, utilities conduct end-to-end testing to ensure the scheme works appropriately and this testing includes both the transmitters and receivers. This paper describes a practical experience of testing a protection relay using a non-conventional test equipment; in addition, it proposes a third party software technique to reveal the contents of the packets transferred on the substation network. The efficiency of electrical Megger’s advanced relay testing software is designed to simplify the complex task of relay testing. 5.
