Product Description
Voltage levels
• Typically used for medium voltage distribution up to around 12kV on the primary side.
• Step down voltage to 400V or 690V on the secondary side.
• Suitable for applications with transformer capacities up to around 1600kVA.
Design Specifications
• Enclosure protection rating of IP54 or higher to protect against dust and occasional splashing of water.
• Insulation class of at least E (140°C) for transformers and switchgear.
• Equipment and components meet IEC standards for electrical substations.
• Optional protective devices like surge arresters, instrument transformers, etc.
Temperature Control
• Natural or forced air cooling systems to dissipate heat from components.
• Temperature sensors to monitor ambient and internal temperatures.
• Temperature control units to regulate fan speeds, activate alarms, etc.
• Heat exchangers or liquid cooling for high ambient temperatures.
• Optional air conditioning for extreme conditions.
Operational Safety
• Integrated protection relays and circuit breakers for overcurrent, overload and short-circuit protection.
• Optional protective relaying for earth faults, over/under voltages, reverse power, etc.
• Islanding prevention to automatically disconnect from the grid during outages.
• Fire suppression systems and protective earthing.
• Alarms, indicators and control panels for monitoring and operation.
• Security measures like locking doors and intruder detection.
