In the past few years, the focus of various government programmes in the transmission and distribution segments has been on network strengthening, modernisation and ensuring quality power supply. Substations, which convert voltage from high to […]
As electrical grids become more complex with the integration of intermittent renewable energy, grid operators need solutions that are reliable, safe and enable quick decisions in case of an emergency. A digital substation offers precisely […]
Switchgear includes all the devices in power systems that provide protection and regulate power supply. Switchgear de-energises the equipment and clears faults in the system, thereby ensuring reliable power supply. Essentially, it protects the electrical […]
Switchgear requirements differ in conventional substations and automated substations. In a conventional substation, all signals, controls and interlocks are hardwired and records are manually maintained in a logbook. Therefore, a lot of work and effort […]
The need for proper maintenance of switchgear has been increasing over the years as electricity networks are expanding and carrying increasing energy over longer distances. Maintenance of switchgear is critical to maintaining equipment integrity, ensure […]
Long distance transmission of power is one of the focus areas of the power sector. The need for ensuring efficient long distance power transmission emerges from the huge distance between generating stations and demand centres. […]
The different kinds of switchgear can be classified on the basis of their load bearing capacity (or voltage class), the medium used to interrupt the current, the interrupting rating (which is the maximum short circuit […]
The power sector in India has been growing at a healthy pace supported by various policy initiatives by the government. Generation capacity has grown at a brisk rate of over 10 per cent over the […]
