- Q2. Man power Handling - Contracts
- Q3. Understanding of IS and root cause of failure
- Ans.
Understanding IS and root cause of failure is crucial for preventing future issues in production.
IS stands for Information Systems, which are used to collect, store, process, and distribute information within an organization.
Root cause analysis is a method used to identify the underlying cause of a problem or failure.
Having a strong understanding of IS can help identify potential failures in the production process and ...

- Q1. Basic question related to electrical and related to what they are manufacturing
- Q2. What is transformer and there working principle?
- Ans.
A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
Consists of two coils of wire, known as primary and secondary coils
Primary coil is connected to a source of alternating current
Alternating current in primary coil creates a changing magnetic field
This changing magnetic field induces a voltage in the secondary coil
Voltage in secondary coil can be hig...
- Q3. Safety devices in transformer?
- Ans.
Safety devices in transformers include pressure relief devices, Buchholz relay, and temperature sensors.
Pressure relief devices are used to release excess pressure in the transformer to prevent explosions.
Buchholz relay is a gas and oil operated relay that detects internal faults in the transformer.
Temperature sensors are used to monitor the temperature of the transformer and prevent overheating.
- Q4. Controlling devices in the transformer and there working and why we are using?
- Ans.
Controlling devices in transformers are used to regulate voltage, protect against overloads, and ensure efficient operation.
Controlling devices such as tap changers are used to adjust the voltage ratio of the transformer to maintain a constant output voltage.
Protective devices like relays are used to detect and isolate faults such as overloads, short circuits, and overvoltage conditions.
Monitoring devices like temperat...
- Q5. What are delta connection and star connection why we use and when and where we use ?
- Ans.
Delta connection and star connection are two types of connections used in electrical circuits. Delta connection is used for three-phase systems, while star connection is used for single-phase systems.
Delta connection is used in three-phase systems where the load is balanced and the power requirement is high.
Star connection is used in single-phase systems where the load is unbalanced and the power requirement is low.

- Q3. Different between relay and contactor
- Ans.
Relays are used for low power applications while contactors are used for high power applications.
Relays are typically used in control circuits to switch low power loads such as lights and fans.
Contactors are used to switch high power loads such as motors and compressors.
Relays have a lower current rating than contactors.
Contactors have larger contacts and can handle higher currents than relays.
Relays are typically smal...
- Q4. Different between switch and relay
- Ans.
Switches are used to control the flow of current in a circuit, while relays are used to switch a circuit on or off.
