What are the hazards of transformers?

Transformers’ hazards make risk management crucial. Core risks in their operation and maintenance include:

● Fire and explosion: Many transformers contain insulating mineral oils that are highly flammable. Overheating caused by a fault, surge, or extreme weather conditions may cause catastrophic fire damage without adequate transformer fire protection solutions.

● Arc flashes and blasts. Connection between a live conductor and another conductor or the ground may release sudden heat and light. The resulting arc blast generates exceptional heat and releases shrapnel, posing severe injury risks. Causes of arc flashes include worn or damaged insulation, incorrect installation, and equipment failure due to poor maintenance.

● Oil leaks: Older transformers that use oil for insulation and cooling may leak coolant if not maintained. Leaked fluids create slipping hazards and fire hazards if oil ignites. Electrical shocks. Transformers may expose technicians to high-voltage electrical currents. In addition to power transformer fire protection, operators and technicians must wear protective equipment and keep to safety regulations.
