Not Completed Nuclear Power Plant 

Jaitapur Nuclear Power Project Jaitapur Nuclear Power Project is the well-known power plant and a proposed project of Nuclear Power Corporation of India. Once built, it will be the largest nuclear power generating station. The project comprises of six European pressurized reactors each with a capacity of 1650 MW. These reactors are considered to be the third-generation pressurized water reactors.

Kovvada Nuclear Power Plant Kovvadu Nuclear Power Plant is the proposed light and water nuclear power reactors. The plant is proposed to be set at Kovvada in Srikakulam district. According to the proposed plan, six 1000 MW light water nuclear power reactors need to be built. However, there are many political parties and leaders who are opposing the power plant construction owing to safety issues.

H.V. Testing (High Voltage Testing)

High voltage tests are carried on different machines to check the under high voltage for a shorter time to check the quality of healthiness insulation resistance.

In this test specified voltages is applied between various windings and earth. This test should be carried out together with the insulation resistance test at manufacturer's works. Generally high voltage test is applied only if insulation resistance is less than the specified limit.

Method of testing:

The test shall be made with alternating voltage of any convenient frequency between 40 Hz to 60 Hz. The test voltage should be of sine waveform (approximately).

Duration:

 The test is started by applying 1/3rd of the test voltage and then voltage is increased to full-test voltage in accordance with the Table


This test checks the weakness of insulation, damaged insulation etc.

Leakage Current Test of Motors and Electrical Machine

leakage current should be negligibly small so that there is no risk to the operator and operator and machine is safeguarded. The limit for the current so measured by the external circuitry shown in the diagram shall not be more than 2.5 mA



Procedure:

  • The motor is applied with a voltage 1.1 x rated voltage through auto transformer.
  • An external circuit consisting of a mili ammeter and a resistance R = 2000± 50 value is connected as shown in the diagram. For the perfect condition of the insulation of the motor, the mili ammeter reading should not exceed 2.5 mA

KIRCHHOFF'S LAWS (Electrical Networks)

The entire electric circuit analysis is based on Kirchhoff's laws only. But before discussing this, it is essential to familiarise ourselves with the following terms:
(a) Node :-  A node is a junction where two or more circuit elements are connected together.
(b) Branch:-  An element or number of elements connected between two nodes constitutes a branch.
(c) Loop :- A loop is any closed part of the circuit.
(d) Mesh :- A mesh is the most elementary form of a loop and cannot be further divided into other loops. All the meshes are loops but all the loops are not meshes.

(1) Kirchhoff's current law (KCL) :- The algebraic sum of currents meeting at a junction or node in an electric circuit is zero.
Consider five conductors, carrying currents i1,i2,i3,i4 and i5, meeting at a point O as shown in Fig.



Assuming  the incoming current  to be positive and outgoing currents negative, we have

Thus, above law can also be stated as the sum of currents flowing towards any junction in an electric circuit is equal to the sum of the currents flowing away from that junction.

2. Kirchhoff's voltage law (KVL)
The algebraic sum of all the voltages in any closed circuit or mesh or loop is zero.
If we start from any point in a closed circuit and go back to that point, after going round the circuit, there is no increase or decrease in potential at that point. This means that the sum of EMFs and the sum of voltage drops or rises meeting on the way is zero.

Determination of sign   A rise in potential can be assumed to be positive while a fall in potential can be considered negative. The reverse is also possible and both conventions will give the same result.

(a) If we go from the positive terminal of the battery or source to the negative potential and so the emf should be assigned a negative sign. If we go from the negative terminal of or source to the positive terminal, there is a rise in potential and so the emf should be given positive sign.


(b) When current flows through a resistor, there is a voltage drop across it. If we go through the resistance in the same direction as the current, there is a fall in the potential and so the sign of this voltage drop is negative. If we go opposite to the direction of the current flow, there is a rise in potential and hence, this voltage drop should be given a positive sign.
