In 2022, Bharat Heavy Electricals Ltd. (BHEL) has produced a Bus Potential Transformer Module, first of its kind to be developed by an Indian manufacturer. In the existing design, a separate Potential Transformer(PT) panel was provided, having the same size, weight and cost as a regular feeder panel.
A capacitor voltage transformer (CVT), is a transformer used in power systems to step down extra high voltage signals and provide a low voltage signal to the actual VT (voltage transformer) used for operating metering/protective relays due to a lower cost than an electromagnetic PT.

Bharat Heavy Electricals Limited, Jhansi is a factory and township in Uttar Pradesh, India. It was founded on 9 January 1974 and is one of the 17 manufacturing units of the Bharat Heavy Electricals Limited (BHEL) Corporation. It is located on NH-44, 15 km south of Jhansi city. The Jhansi unit is spread in 1,064 acres (431 ha), which includes ...
The transformers are wired together on the secondary side. The system is arranged so that nearby transformers do not use the same feeder. In case of an issue with a feeder (or transformer) the load is fed by nearby transformers, so there is no interruption, although a voltage drop for said load may then be present.
A transformer supplying a three-wire distribution system has a single-phase input (primary) winding. The output (secondary) winding has a center tap connected to a grounded neutral. As shown in Fig. 1, either end to center has half the voltage of end-to-end. Fig. 2 illustrates the phasor diagram
In electrical engineering, isolated-phase bus (IPB), also known as phase-isolated bus (PIB) in some countries, is a method of construction for circuits carrying very large currents, typically between a generator and its step-up transformer in a steam or large hydroelectric power plant. Isolated phase bus during installation at the Bui Dam Ghana ...

The electromagnetic voltage transformer is a wire-wound transformer. The capacitor voltage transformer uses a capacitance potential divider and is used at higher voltages due to a lower cost than an electromagnetic VT. An optical voltage transformer exploits the electrical properties of optical materials. [15] Measurement of high voltages is ...
