Tata utilises ABB switchgear for Mumbai substations

ABB’s hybrid switchgear technology enabled Tata Power to increase the capacity and reliability of 10 substations in Mumbai.

ABB’s plug and switch system or PASS hybrid switchgear is a gas-insulated switchgear module for air-insulated distribution substations that have space restrictions or severe climatic conditions to contend with. The PASS M0 module solves space restrictions in big cities.

It incorporates all the functions of a switchgear bay - circuit breaker, disconnector, earthing switch, current and voltage transformers, and SF6 density monitoring equipment - in one single, highly compact pre-assembled and factory-tested module.
The conventional alternative to PASS is a switchgear bay, made up of individual components that are separate items of equipment, each needing their own concrete foundation, wiringnd connections.

The highly compact installation requires less than half the space of conventional solutions, is quick to set up and delivers lower cost of ownership over the product life cycle. For Mumbai, India’s most populous city and the commercial, industrial and financial capital of the Indian economy, the technology is a perfect fit.

“Tata Power has a long-standing relationship with ABB. We value your technology, expertise and support for the success of our projects and subsequent operation,” said  Sanjay Patki, Head of Engineering, Procurement & Technical Services Tata Power Company Ltd.

ABB initially provided Tata Power with 19 PASS M0 145 kV switchgear modules to boost the capacity and reliability of eight distribution substations in Mumbai. Tata Power has ordered an additional four modules for a further two substations.
