Pomanique Electric Co., Ltd. 
Grid connection equipment prepared for variable generation.
Solar, wind, battery storage and distributed generation projects require reliable isolation, fault interruption and surge protection between generation equipment and the utility network. Pomanique provides medium-voltage products that support collector circuits, step-up substations and grid interconnection points.
Key system requirements
Bidirectional power flow
Protection and switching must respond correctly across changing generation and grid operating conditions.
Surge exposure
Outdoor collector networks need coordinated protection against lightning and switching overvoltage.
Remote operation
Reclosers, breakers and controls should support monitoring and operating requirements at dispersed sites.
Recommended equipment configuration
- Vacuum circuit breakers and reclosersFault interruption and automatic sectionalizing at collector feeders and interconnection points.
- Disconnectors and load break switchesSafe isolation for inverter stations, transformers, storage systems and maintenance zones.
- Surge arresters and composite insulatorsOutdoor insulation coordination for exposed renewable-energy sites.
- Controls, relays and MV transformersProtection, measurement and voltage transformation matched to the grid connection scheme.
Project support
Send the plant capacity, system voltage, interconnection standard, short-circuit data, transformer parameters and communication requirements. Pomanique will help identify suitable ratings and coordinate the medium-voltage equipment package.
