Transformer Explosion and Impact on the Reinforced Blast Wall

Transformer is one of the vital equipment to provide stable and reliable electricity to the community. The transformer is quiet while in operation, therefore it is hardly to realise if placed inside the building. The price for one transformer can be up to few millions Malaysian Ringgit. The worst of...
