Shunt Reactors
Shunt Reactors
Shunt Reactors IS 5553, of tests performed in an EHV or UHV shunt reactor, can categorize in a there different groups.
- Type tests
- Routine tests
- Special tests.
Type Tests of Shunt Reactor
The following tests are essentially performed on a shunt reactor as type tests- Measurement of Losses.
- Dielectric Withstand Tests
- Routine Tests of Shunt Reactor
- Measurement of Losses.
- Dielectric Withstand Tests
Special Tests of Shunt Reactor
The following test is essentially performe in the shunt reactor the special tests- Measurement of Zero Sequence Reactance.
- Measurement of Mutual Reactance.
- Measurement of Acoustic Sound Level..
- Measurement of Magnetizing Characteristics
- Measurement of the tan delta of winding.
- Dissolved Gas Analysis of Insulating Oil.
As per IS 5553, the tests performed on associate degree EHV or UHV shunt reactor may be categorised in 3 completely different teams.
Type tests
Routine tests
Special tests.

The following 2 factors to be thought-about throughout activity of electrical phenomenon of a shunt reactor.
The electrical phenomenon of a shunt reactor is about adequate its electrical phenomenon because the resistive element of the electrical phenomenon in shunt reactor is negligible.
The V – I characteristics of the shunt reactor is sort of linear underneath operative varies of applied voltage. this can be as a result of, a gapped core is employed within the shunt reactor to forestall magnetic saturation of the core inside traditional operational vary.

For three section reactors with magnetic iron path for zero sequence flux, zero sequence electrical phenomenon is also measured as follows,
In that case the 3 terminals of the reactor ar shorted and single section offer is applied between common section terminal and neutral terminal of the winding. once measure the present through the common path we've got to divide the applied single section voltage by it. we have a tendency to then multiply three with the result to get zero sequence electrical phenomenon per section.
