This 5-day training course is aimed at electrical engineers and technicians responsible for the specification, purchase, installation, commissioning, operation, inspection, maintenance, and repair of MV & HV & LV switchgear in Power Substations.
This course focuses mainly on medium voltage switchgear associated with power distribution in industrial Power Substations systems, which comprises by far the bulk of switchgear on most electricity distribution systems. The emphasis is primarily on air-break, SF6 and vacuum circuit breakers, but other forms of MV switchgear, for example ring main units and auto re-closers will also be discussed. Gas insulated substation, (GIS), for higher voltages will be discussed in some detail.
Key topics covered in this training course include:
- Types and rating of switchgear - substation layouts and design - indoor and outdoor.
- Switchgear components CT’s, VT’s, protection relays and cable terminations
- Calculation of substation fault levels
- Basic earth fault, unit and overload protection schemes
- Safe operational policies, including safety rules and safety documents
- Asset management of substation equipment
- Diagnostic tools - insulation testing, partial discharge testing, thermal imaging, and potential test equipment.
- Make and break testing of trip and contact systems test equipment
- Safe maintenance policies, including safe working practice in switch rooms, indoor and outdoor substations
- National fault reporting schemes
- Earthing
