The Megger SVERKER650 is a powerful, compact and simple-to-use relay test set suitable for testing a wide variety of power, voltage and current relays.

Created with years of experience, the SVERKER 650's intuitive interface, powerful functionality and other features combine together to create a comprehensive system for fully testing virtually all types of single phase protection.

Made for use in both high voltage substations and industrial conditions, the SVERKER650 includes a built-in capacitor to provide phase shift when testing directional protective relays and also has built-in resistors to divide voltages as and when needed.

The SVERKER650 is compact and portable enough to easily be transferred from testing point to testing point and is supplied as standard with a rugged carrying case.
