In power stations require electricity for use in the power station. Electric power for use in the power station is used for: 1. Lamp lighting 2. Conditioning air 3. Starting aids generating units, such as cooling water pump, lubricating oil pump, fuel oil transfer pump, lifting machines, and others. 4. Charging batteries battery which is a source of direct current ...

Conditions transformer can also be analyzed on the basis of the analysis of the acoustic vibrations emitted parts transformer parts. This method can be carried out, on line. Basis. off line transformer condition can be checked by measuring the resulting current when a voltage of 10 volts injected the altered frequency (a few kilo Hertz) a. Transformer relationship deltas 3 ...

Various kinds of electrode were used for this test is to obtain test results in case of failure of transformer oil pressure oil volume, uniform and non-uniform field. 1) Transformer Oil Processing Dielectric strength of the transformer oil is strongly influenced by processing and testing conditions, as it determines the quality of   transformer oil during testing. The nature of ...

Some transformer oil purification methods are described in the following sections: 1) Boiling Oil is heated to the boiling point of water in a device called a boiler. The water in the oil will evaporate because the boiling point of oil is higher than the boiling point of water. This method is the simplest method but has its drawbacks. First ...

1. The switch function Function switch disconnect and reconnect the electrical circuit. The higher voltage systems which are connected and disconnected to the system, the more difficult process of facing disconnection of electric circuits because the higher the voltage, the higher the voltage transient at the time of disconnection in the circuit. Voltage transients can bring back the electric current ...
