Manufacturing and Testing of Instrument Transformer

Ohol Gayatri Sanjay

BE-Div. B (2023-2024 Batch), Electrical Engineering

gayatrisohol@gmail.com

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).

Automatic Power Factor Correction

Girase Sakshi Sham,

TE-B, Electrical Engineering

girasesakshi1@gmail.com

Welcome to this newsletter on Automatic Power Factor Correction (APFC) Panels, where we'll be discussing what APFC Panels are, their benefits, and how they can help improve the industry's business.

What are APFC Panels?

APFC Panels are electronic devices used to automatically control the power factor of an electrical system. Power factor is a measure of how effectively electrical power is being used. If the power factor is low, it means that the system is wasting energy. APFC Panels work by monitoring the power factor and adjusting the voltage and current supplied to the system to improve the power factor and increase energy efficiency.

Benefits of APFC Panels

APFC Panels have numerous benefits, including:

1.      Energy Efficiency: APFC Panels can significantly improve energy efficiency by optimizing the power factor of your electrical system. This reduces energy consumption, which in turn lowers energy costs and reduces the carbon footprint of your business.

2.      Reduced Electricity Bills: Improved power factor means that we will be using less electricity, which will result in lower electricity bills.

3.      Longer Lifespan of Electrical Equipment: By optimizing the power factor, APFC Panels can reduce the stress on electrical equipment, resulting in a longer lifespan and lower maintenance costs.

4.      Improved Voltage Stability: APFC Panels can help stabilize the voltage of your electrical system, which can improve the performance of your equipment and reduce the risk of damage caused by voltage fluctuations.

 

5.      Compliance with Regulations: Many countries have regulations in place that require industries to maintain a certain power factor. APFC Panels can help industries comply with these regulations.

How do APFC Panels work?

APFC Panels work by monitoring the power factor of the electrical system and adjusting the voltage and current supplied to the system to improve the power factor. The panel includes a microcontroller that continuously monitors the power factor and adjusts the voltage and current supplied to the system. The panel also includes capacitors that are used to store and release electrical energy to improve the power factor.

When the power factor is low, the microcontroller signals the capacitors to release electrical energy, which is then used to compensate for the reactive power in the system. This helps to improve the power factor and reduce energy consumption.

Key Features of APFC Panels

APFC panels incorporate various features that enhance their functionality and performance. Some notable features include:

a.      Capacitor Bank: APFC panels consist of a capacitor bank that stores and releases reactive power as required. The capacitor bank is controlled by a microprocessor-based automatic controller that continuously monitors and adjusts the power factor.

b.      Intelligent Controller: APFC panels are equipped with intelligent controllers that analyze real-time power factor data and issue commands to the capacitor bank. These controllers ensure accurate and timely correction of the power factor, optimizing the system's performance.

c.       Protection Mechanisms: APFC panels are designed with built-in protection mechanisms such as overvoltage, undervoltage, and overcurrent protection. These safeguards protect the electrical system from potential damage due to voltage fluctuations and other anomalies.

Mathematical modeling of APFC

power factor = Real power(kW) / apparent power (KVA)

In a purely linear circuit,

Power factor = cos θ

where θ is the angle between the real power and the apparent power in the vector power triangle below.

 

A power factor closer to 1 provides the maximum utilization of power drawn from the grid. A low power factor indicates inductive or capacitive elements in the circuit causing the current drawn to lag or lead the voltage, respectively, decreasing the instantaneous real power available to the load and consuming unnecessary current capacity on the cables

For nonlinear circuits, the power factor is affected by an additional distortion component resulting from the harmonics in the line current.

Power Factor=cos θ∗(1/√(1+TotalHarmonicDistortion^2)

Results:

Conclusion

APFC panels are essential components of efficient power management systems. By maintaining a balanced power factor, APFC panels reduce energy consumption, enhance equipment lifespan, and contribute to overall energy savings. We hope this newsletter has provided valuable insights into APFC panels and their benefits.
