• Strong communication skills and the ability to supervise teams on-site.

It is required that the applicant to be experienced in the principles of:

• 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.
