Pomanique Electric Co., Ltd. 
Clear protection zones and dependable switching for substations.
Substations need accurate protection, reliable interruption and safe isolation across incoming lines, busbars, transformers and outgoing feeders. Pomanique equipment supports conventional and remotely operated substations with coordinated switching, protection and insulation products.
Key system requirements
Selective protection
Define clear zones so the nearest breaker operates first while healthy substation sections remain energized.
Operational safety
Combine interruption and visible isolation with procedures suitable for inspection and maintenance.
Control integration
Match breakers and relays to local control, remote indication and substation automation requirements.
Recommended equipment configuration
- Vacuum or SF6 circuit breakersIncoming, transformer, bus-coupler and feeder interruption selected for the required fault duty.
- Disconnectors and load break switchesIsolation and operational switching for planned work and network configuration changes.
- Protection relays and controlsOvercurrent, earth-fault and transformer or feeder protection with appropriate coordination.
- Surge arresters and MV transformersTransient protection, voltage transformation and measurement for substation equipment.
Project support
Share the single-line diagram, voltage and fault levels, breaker operating sequence, CT/VT data, relay functions and communication protocol. Pomanique will help align product parameters with the substation protection concept.
