- Q2. What is power factor
- Ans.
Power factor is a measure of how effectively electrical power is being used in a circuit.
Power factor is the ratio of real power to apparent power in a circuit.
It is a number between 0 and 1, with 1 representing perfect efficiency.
A low power factor indicates inefficient use of electrical power.
Power factor can be improved by using power factor correction devices.
For example, inductive loads like motors have a lower po

Interview Questionnaire
4 Questions
- Q1. Types of transformer
- Ans.
Types of transformers include power transformers, distribution transformers, autotransformers, isolation transformers, and instrument transformers.
Power transformers are used to step up or step down voltage in power transmission systems.
Distribution transformers are used to step down voltage for distribution to consumers.
Autotransformers have a single winding and are used for voltage regulation.
Isolation transformers p...
- Q2. Motor maintenance
- Q3. What is ir test
- Ans.
IR test stands for Insulation Resistance test which is used to measure the resistance of insulation material.
IR test is used to check the quality of insulation material used in electrical equipment.
It helps to detect any insulation failure or breakdown in the equipment.
The test involves applying a high voltage to the insulation material and measuring the current flowing through it.
The measured resistance value is compa...
- Q4. What is ct g
- Ans.
CT stands for Current Transformer, a device used to measure electrical current.
CT is a type of transformer that steps down high current to a lower, measurable level.
It is commonly used in power systems to measure current flowing through a circuit.
CTs are also used for protection purposes, such as detecting overcurrent or short circuits.
CTs can be either solid-core or split-core, with the latter being easier to install.
