1   Introduction to CT and PT

Instrument transformers (ITs) are designed to transform voltage or current from the high values in the transmission and distribution systems to the low values that can be utilized by low-voltage metering devices. There are three primary applications for which ITs are used: metering (for energy billing and transaction purposes); protection control (for system protection and protective relaying purposes); and load survey (for economic management of industrial loads). Depending on the requirements for those applications, the IT design and construction can be quite different. Generally, the metering ITs require high accuracy in the range of normal operating voltage and current. Instrument transformers are the most common and economical way to detect a disturbance. Typical output levels of instrument transformers are 1-5 amperes and 115-120 volts for CTs and VTs, respectively.

Figure 1. Current and Voltage Transformer Symbols and Simplified Concept

2. Types of insulation

There are different types of insulation are used in instrument transformers according to their dielectric breakdown strength, The primary and secondary coils of a transformer are the key components in performing its basic function of transforming voltage and current. Materials are used to insulate the primary and secondary coils. In transformers, in addition to the primary and secondary coils, there are several other important components and accessories. The insulating material is one of the most critical components of a transformer. Sufficient insulation between different active parts of the transformer is necessary for its safe operation.

3. Type of Core

The transformer core is an iron block that acts as a path for the flow of magnetic flux. Thus, the transformer core forms the magnetic circuit of the transformer. It is used to confine the magnetic flux to a definite path. The transformer core acts as the housing for the primary and secondary windings of the transformer in addition to providing a path for the magnetic flux. As we know, a transformer works on the principle of mutual inductance. According to this principle, the magnetic flux produced by one winding (primary winding) links to another winding (secondary winding) to produce a transformed voltage or current. These two windings are electrically isolated and magnetically coupled to each other. It is also known that the opposition in the flow of magnetic flux is referred to as magnetic reluctance. It will cause a reduction in the amount of magnetic flux due to the high reluctance of air or non-ferrous material.

4.  Type of Winding

Transformer winding includes different turns of copper coil bundles where every bundle is connected to form a winding. Windings mainly depend on the input-output supply otherwise on the range of voltage. Transformer winding is available in two types, i.e. primary winding and secondary winding. Transformer winding operation is, that the primary winding gets electrical energy from the source whereas secondary winding transmits electrical energy to the load. Transformer winding materials are aluminium and copper which are the most frequently used conductors in transformer windings.

5.  Molding and Finishing

Epoxy resin:- Hardener, silica powder, colour paste and plasticizer are mixed together to    make insulation

7. Conclusion

CT reduces the large current to a safer and measurable level and PT reduces the high voltage to a safer and measurable level, Current transformer is a voltage step-up and current step-down transformer and the Voltage transformer is a voltage step-down and current step-up transformer.

Welcome to the Newsletter on Instrument Transformers, where we will be discussing what are Instruments Transformers, their Manufacturing Process, and Testing of Instrument Transformers.

1. Introduction to Instrument Transformers

Generally, High voltages and currents are quite dangerous to work with & the instrument we use such as Ammeter & Voltmeter cannot handle such a high level of voltage and current. For this specific purpose, instrument transformers are used that reduce it to a safe level allowing continuous monitoring of high voltage and current. CT & PT are manufactured to suit various environmental conditions confirming various standard specifications such as IS 2705, IS 3156, IEC 61869, BS 3839, etc.

CT & PT are the two Instrument transformers used to measure High current and Voltage.

Functions of Current Transformer:

1. To reduce the line current value to a value that is suitable for standard measuring instruments.

2. To protect the measuring instrument against short circuit current.

3. To sense the abnormalities in current

Functions of Potential Transformer:

1. To measure High Alternating Voltage in a Power System

2. Used for protection and measurement purposes in a Power system

Fig.1 Current Transformer Circuit

Fig.2 Potential Transformer Circuit

2. Classification of Instrument Transformer:

Classification based on Insulation:

The type of insulation depends on the voltage level of the Transformer

1. Air Cooled                                      

2. Dry-type Transformer

3. Oil Cooled Transformer

4. Gas filled

Classification based on Voltage level:

1. Low voltage transformer

2. High voltage transformer

Classification based on Construction:

1. Ring type

2. Window type

3. Rectangular bar type

3. Raw Material Required for Manufacturing of Instrument Transformers:

Copper wire, Insulation paper – Kraft paper, Crepe paper, Sandwich paper, fiber glass paper, Semiconducting paper, Mounting plates, Epoxy resin, Core, etc.

4. Manufacturing Process Flow Chart For Instrument Transformer

5. Testing of Instrument Transformer

1. High Voltage (HV) Test

Electrical equipment must be capable of withstanding overvoltages during operation. Thus by suitable testing procedure, we must ensure that this is done. High voltage testing can be broadly classified into testing of insulating materials (samples of dielectrics) and tests on completed equipment. The tests were carried out on samples of dielectric consist generally of the measurement of permittivity, dielectric loss per unit volume, and the dielectric strength of the material.

The breakdown voltage tests on completed equipment are only done on a few samples since it permanently damages and destroys the equipment from further use. However since all equipment has to stand up to a certain voltage without damage under operating conditions, all equipment are subjected to withstand tests on which the voltage applied is about twice the normal voltage, but which is less than the breakdown voltage. 

Fig.3 HV testing

2. Polarity test

The polarity test of the transformer mentions the relative direction of the induced voltage between the HV & LV winding.

Connect the P1 & P2 of test kit to P1 & P2 of CT

Connect the S1 & S2 of test kit to S1 & S2 of CT

If the polarity is Right, the Deflection is on the positive side

If the polarity is wrong, the Deflection is on the left side

Fig. 4 Polarity test Connections

3. Toroidal Core test

We can measure the current of the primary winding and voltage from the secondary winding to find losses, Induction & magnetizing force of the toroidal core.

1. Mains ON

2. Power ON

3. Apply Calculated Voltage

4. Measure Practical Current

5. If the measured current is less than the theoretical current then CT is ok

6. If the measured current is greater than the theoretical current then CT is not ok.

Fig.5 Torridal core test setup

Conclusion:

The Instrument transformers are designed so that the ratio of actual voltage or current values to the metered values can be established to the necessary degree of accuracy. Generally Instrument transformers are used for 3 purposes: metering (for energy billing and transaction purposes); protection control (for system protection and protective relaying purposes); and load survey (for economic management of industrial loads).
