SVERKER 900 data sheet - .PDF file.

The SVERKER 900 protection relay and substation test system from Megger provides engineers with a range of tools that cover all major requirements for single- and three-phase testing in distribution substations, renewable power generation installations and industrial applications.

SVERKER 900 incorporates three current generators and four voltage generators, the amplitude, phase angle and frequency of which can be individually adjusted. In addition, the current and voltage generators can be connected in parallel or series to provide single-phase outputs of up to 105A and 900A. This means that although the test set is principally designed for secondary testing of protection devices, in many applications it can also be used for primary testing.

To complement the current and voltage generators, the SVERKER 900 features a large colour touchscreen that provides an intuitive user interface and a powerful internal processor that eliminates the need to use an external computer for most types of manual and semi-automatic testing.

The touchscreen provides access to a range of pre-configured virtual test instruments. The main virtual instrument provides timing tests as well as options for the manual determination of relay pick-up and drop-out points together with general facilities for generating, injecting and measuring currents and voltages.

Other virtual instruments include a CT magnetisation instrument, a pre-fault instrument, a ramping instrument and a sequence instrument. An impedance instrument is also provided, which allows relays to be tested directly from the impedance plane, with conversion from impedance to voltages and currents carried out automatically by the SVERKER 900 test set.
