Job Description
- High Voltage Testing (415v – 33kv systems)
- CT Magnetisation Curves – being able to complete using variac/volt & ammeter as well as CT analyser. Also, polarity check without CT analyser.
- CT Primary Injection – standard protection (OC/EF/Metering) configuration & high impedance scheme such as Bus Zone protection.
- Relay Secondary Injection (Both electromechanical and solid-state relays) – to include current & voltage protection.
- VT Primary Injection
- Control Circuit Wiring testing & modification. – prove each panel to the associated schematic diagram & fault find. Must be able to read schematic diagrams.
- Mechanical/Electrical function testing of 415v – 33kv switchboards & networks
- G59 G99 protection – Under/Over Voltage, Under/Over Frequency, ROCOF/dF/dT.
- Must be familiar with basic secondary Injection sets such as Sverker 760/780, T&R 100/200ADM, T&R DVS3.
- Knowledge of B.E.B.S. S12 (1964) wire identification standard as used in all UK HV switchgear.
- Knowledge of basic transformer protection devices & associated test methods.
- Operational knowledge of basic auto-changeover schemes.
