Isolated Phase Busduct is a custom designed Busbar system enclosed in an aluminium duct forming the interconnection between Generator and Generator Transformer through Generator Circuit Breaker. Taps are taken to Unit Auxiliary Transformer, LAVT cubicle, Excitation Cubicle etc.

The Design & Construction of IPB are such that it reduces the short circuit forces to a very minimum, theoretically zero and also prevents the electromagnetic interference with a neighbouring steel structure. This system ensures high reliability of the inter connection, which is one of the most vital and critical element in the successful operation of the Generating station. Powergear has 35 years of experience in designing and supplying such a highly reliable equipment for hundreds of Generators in about 20 countries throughout the world.
