We have dedicated team of experts for Testing & Commissioning services of all types of Protection Relays, Control & Relay Panels, Switchgear Panels, Transformers, Motors and Sub-stations up to 220KV.
The testing of protection equipment may be divided into four stages :
- Type tests
- Routine factory production tests
- Commissioning tests
- Periodic maintenance tests
- The Megger (Programma) SVERKER 750 Protection Relay Test Kit is used for single phase relay testing. The SVERKER 750 Protection Relay Test Kit features a powerful measurement section which displays(in addition to time, voltage and current) Z, R, X, S, P, Q, phase angle and cos f.
