The SVERKER 750 features a multi-mode display which makes relay testing more efficient. Time, voltage, current, impedance (Z), resistance (R), reactance (X), virtual power (S), active power (P), reactive power (Q), phase angle (φ) and power factor (cos φ) can all be displayed.
The SVERKER 750 can test directional protective equipment due to an inbuilt variable voltage source, as well as protective devices which automatically reclose after operation.
Three phase protective equipment can also be tested, one phase at a time. Multiple SVERKER units can be connected and synchronised to form a basic three phase test set, applicable for relay protection systems that require phase shifting.
The SVERKER 750 can test the following relays:
In addition to protective relay testing, the SVERKER 750 also offers the following features:
The turning off of generation can be delayed after tripping throughout a specified time interval that is expressed in mains frequency cycles.
