Interconnecting transfomers are used to connect two EHV line at different voltages i.e. KV to KV. The interconnecting transformer are. Transformers for Interconnecting High-Voltage Transmission Systems For Feeding Synchronous Condensers from a Tertiary Winding. Abstract: Owing to the.

The function of any transformer is to change one AC voltage value to another AC voltage value. A step down transformer will transform a higher AC voltage to a lower AC voltage….
A step up transformer will transform a lower Interconnecting transformer voltage to a higher AC voltage.
The maximum iron and copper loss in these transformers is recorded at the time of peak load. They are normally auto-transformers and they will have a delta connected tertiary winding of about 33kV voltage rating, for providing a circulating path for the zero-sequence currents.
A zig-zag transformer provides a path for current that is common to all three phases so-called zero sequence current. Audio system[ edit ] In audio applications, interconnecting transformer autotransformers are used to adapt speakers to constant-voltage audio distribution systems, and for impedance matching such as between a low-impedance microphone and a high-impedance amplifier input.
To increase the distance between electricity Grid feeder points, they can be arranged to supply a split-phase kV feed with the third wire opposite phase interconnecting transformer of reach of the train's overhead collector pantograph. The 0 V point of the supply is connected to the rail while one 25 kV point is connected to the overhead contact wire.

This system increases usable transmission distance, reduces induced interference into external equipment and reduces cost. A variant is occasionally seen where the supply conductor is at a different voltage to the contact wire with the autotransformer ratio modified interconnecting transformer suit.
Variable autotransformers[ edit ] A variable autotransformer, with a sliding-brush secondary connection and interconnecting transformer toroidal core. Purpose of bus coupler in switchgear: Bus coupler is using with two incoming buses.
