- Q1. What is the DC and AC motor
- Ans.
DC motors use direct current to generate rotational motion, while AC motors use alternating current.
DC motors have a commutator and brushes to switch the current direction, while AC motors do not.
AC motors are more commonly used in household appliances, while DC motors are used in electric vehicles and industrial machinery.
Examples of DC motors include brushed and brushless motors, while examples of AC motors include i
- Q2. Types of current
- Ans.
There are two types of current - AC and DC.
AC stands for Alternating Current and changes direction periodically.
DC stands for Direct Current and flows in one direction only.
AC is used for power transmission over long distances while DC is used for electronic devices.
Examples of AC sources include power grids and generators while batteries are a common source of DC.
AC voltage can be stepped up or down using transformers...

- Q1. 1.what is composite error and ratio error in current transformer?
- Ans.
Composite error and ratio error are two types of errors in current transformers.
Composite error is the combination of ratio error and phase angle error in a current transformer.
Ratio error is the difference between the actual turns ratio and the specified turns ratio of a current transformer.
Phase angle error is the angular difference between the primary and secondary currents of a current transformer.
Composite error a...
- Q2. 2.Draw ckt diagram of a.c drive.
- Ans.
An AC drive circuit diagram controls the speed of an AC motor by varying the frequency and voltage of the power supplied to it.
An AC drive consists of a rectifier, DC link, inverter, and control circuitry.
The rectifier converts AC power to DC power, which is stored in the DC link.
The inverter converts the DC power back to AC power with variable frequency and voltage.
The control circuitry adjusts the frequency and volta...
- Q3. 3.Draw single line diagram of distribution system with proper secification.
- Ans.
A single line diagram of a distribution system is required with proper specifications.
The diagram should show the flow of power from the source to the load
It should include all components such as transformers, switchgear, and cables
The specifications should include voltage levels, power ratings, and protection devices
The diagram should follow standard symbols and conventions
Example: A 11 kV distribution system with a 5
- Q4. 4.Why do the dewpoint test in transformer?
- Ans.
Dewpoint test is done in transformer to check the moisture content in the insulation oil.
Moisture in insulation oil can cause breakdown of transformer insulation
Dewpoint test helps to determine the moisture content in the oil
It is a preventive maintenance measure to avoid transformer failure
The test involves cooling a mirror until dew forms on it, and measuring the temperature at which dew forms
- Q5. 5.What is the difference between power transformer and distribution transformer?
- Ans.
Power transformers are used in transmission systems to step up or down voltage, while distribution transformers are used in distribution systems to step down voltage.
Power transformers are used in high voltage transmission systems to step up or down voltage for long distance transmission.
Distribution transformers are used in low voltage distribution systems to step down voltage for local distribution.
Power transformers...
- Q6. 6.How to work Buchholz relay in transformer.
- Ans.
Buchholz relay is used to protect transformers from faults by detecting gas and oil flow abnormalities.
Buchholz relay is installed in the pipe connecting the transformer tank and conservator tank.
It operates based on the principle that faults in the transformer generate gases and cause oil flow disturbances.
When gas or oil flow abnormalities occur, the relay trips and sends a signal to the control panel to isolate the ...

- Q1. What is capacity your furnace
- Ans.
The capacity of a furnace refers to its heating output, typically measured in BTUs or tons.
Furnace capacity is determined by the amount of heat it can produce.
It is usually measured in BTUs (British Thermal Units) or tons.
Higher capacity furnaces can produce more heat and are suitable for larger spaces.
For example, a furnace with a capacity of 80,000 BTUs can heat a larger area compared to one with a capacity of 40,000
- Q2. What is drive components in CCM department
- Ans.
Drive components in CCM department are the parts that enable the motor to function properly.
Drive components include motors, gears, belts, and pulleys.
They work together to transfer power from the motor to the machine.
The components must be properly sized and aligned to ensure efficient operation.
Examples of machines that use drive components include conveyor belts, pumps, and fans.

- Q1. Power factor What is vfd Difference between ac and dc motor
- Ans.
Power factor is the ratio of real power to apparent power in an AC circuit. VFD stands for Variable Frequency Drive. AC motors run on alternating current while DC motors run on direct current.
Power factor is a measure of how effectively electrical power is being used in a circuit.
It is calculated by dividing the real power (in watts) by the apparent power (in volt-amperes).
A power factor of 1 indicates that all the pow...
