Current Transformer Manufacturer, Suppliers in Nashik ... Transformers (CT's) are instrument transformers that are used to supply a reduced proportionate value of current to meters, protective relays, and other instruments. CT's provide isolation from the high voltage primary, permit grounding of the secondary for safety, and step-down the magnitude of the measured current to a value that ...
Load break switches - SOCOMEC break switches are devices used to open an electrical circuit by isolating the source from the consumer. Whether they are manual, motorised or with a trip function, these devices ensure the on-load making, breaking and safety disconnection of low-voltage electrical circuits.
Transformers Interview Questions ... - Instrumentation Tools Transformer and Potential Transformer are Instrument transformers. Current Transformer (CT) is a step-up transformer which steps down the current to a known ratio. The primary of this transformer consists of one or more turns of thick wire connected in series with the line.
Electrica: HVDC Transmission transmission now became practical when long distances were to be covered or where cables were required. The increase in need for electricity after the Second World War stimulated research, particularly in Sweden and in Russia. In 1950, a 116 km experimental transmission line was commissioned from Moscow to Kasira at 200 kV. The first commercial HVDC line built in 1954 was a 98 km ...
