An electricity distribution network is responsible for carring electricity from power plants and/or transmission systems and delivering to end users. Typically, the network would include medium-voltage (< 50 kV) power lines, electrical substations and pole-mounted transformers, low-voltage (< 1 kV) distribution wiring and sometimes electricity meters. The equipments involved in the electricity distribution can be complicated and massive.
Electrical Protection Equipments applied to electric power systems to detect abnormal and intolerable conditions and to initiate appropriate corrective actions. These devices include lightning arresters, surge protectors, fuses, and relays with associated circuit breakers, reclosers, etc.
Electrical Protection Equipments cover the following categories:
- Protective relays
- Zone protection
- Fault detection
- Differential protection
- Overcurrent protection
- Distance protection
- Overvoltage protection
- Underfrequency protection
- Reverse-current protection
- Phase unbalance protection
- Reverse-phase-rotation protection
- Thermal protection
