Compact
Substation
A compact substation is used for feeding power from high voltage to low voltage in open cast mines, construction sites in metropolitan cities, etc. The compact substation size is small and suitable for frequent shifting and for use in both indoor and outdoor locations. The substation is installed and mounted on the skid frame, wheels, or channels and is provisioned with lifting hooks.
Advantages
- Compact size with DGPT relay
- All-in-one instrument with gas detection, pressure control, oil temperature, and level control
- Corrugated tank for compactness
- Energy efficient with BIS specifications
