We have bought a 3-phase relay tester, a Sverker type 900!

SVERKER 900 has been designed mainly for manual single- and three-phase secondary testing of protective equipment. The instrument can also be used for different types of primary testing, as the power and voltage sources can be connected in series and / or in parallel to generate up to 105 A AC or 900 V AC. All three current and four voltage sources can be adjusted individually with respect to amplitude, phase angle and frequency. The fourth voltage source can be used to supply auxiliary voltage to the relay protection or to test relays that require a reference voltage.

We hope to have great use for this in our upcoming projects.
