With Megger SVERKER units, you'll have everything you need to test practically any single-phase relay protection. This relay test set is suitable for use with overcurrent, inverse time, undercurrent, ground fault, directional overcurrent, directional ground fault, overvoltage, undervoltage, directional power and a wide variety of other single-phase protection. It's also suitable for use on three-phase protection - just use the SVERKER780 on one phase at a time or alternatively this relay tester is also suitable for use on phase-shifting protective relay systems plus automatic reclosing devices.

Relay testing provides an affordable solution to protect important electrical equipment components and avoid the several megohms (MΩ)) from the NO (Normally Open) terminal to the COM terminal. This is because the NO As an example, particular emphasis is given by the standards to the current transformer dimensioning formulas that manufacturers are obliged to provide, which now have to be in a standardised mathematical format. In fact, gaining a consensus in the protection relay community about the importance of these formulas for relay users has been one of the most important goals achieved by the TC 95/MT 4 committee. Relay manufacturers are required to carry out extensive testing to comply with this requirement, which will result in benefits that include easier, safer, and more reliable design and engineering of protection systems.

Chair of IEC TC 38 and CENELEC TC 38 “Instrument transformers” and member of IECTC 38 WG 37 and WG 47. A relay coil's resistance always comes with the datasheet of the relay. For example, relay coil resistances Volker Leitloff - Volker is an expert in domain protection and automation with RTE (French TSO). Volker is an active member of the IEC:

Makes it possible to measure voltage and current as short as a quart of a mains voltage period by saving a reading on the display. Voltage and current readings are frozen when the timer stops. If it doesn't stop, the reading present when the current was interrupted is frozen on the display. The following table outlines exactly what each part of the SVERKER650 is capable of. The following image includes reference codes which are also in the table below.

IEC 60255-187-3, Functional requirements for biased (percentage) differential relays for transmission lines Not only should the test engineer be aware of these requirements, but test equipment manufacturers are also expected to implement standardised test methods in their test sets. As these two examples have shown, the standardisation chain extends far beyond the relay manufacturers. COM terminal when the relay isn't energized; thus, there is almost 0Ω resistance between the 2 terminals.
