- Q1. What are undervoltage faults?
- Ans.
Undervoltage faults occur when the voltage in a system drops below the normal operating level, leading to potential equipment damage or malfunction.
Undervoltage faults can be caused by issues such as power supply fluctuations, equipment failures, or overloaded circuits.
These faults can lead to equipment damage, reduced efficiency, or complete shutdown of systems.
Examples include a power surge causing a drop in voltage,...
- Q2. What are overvoltage faults?
- Ans.
Overvoltage faults are electrical faults that occur when the voltage in a circuit exceeds the normal operating range.
Overvoltage faults can damage electrical components and equipment.
They can be caused by lightning strikes, power surges, or faulty equipment.
Protective devices like surge protectors and voltage regulators can help prevent overvoltage faults.
Examples include a power surge from a lightning strike damaging ...

- Q1. What is the purpose of a thermal relay?
- Ans.
A thermal relay is used to protect electrical circuits from overloads by monitoring the temperature of the circuit and tripping when it exceeds a certain threshold.
Monitors the temperature of the electrical circuit
Trips and disconnects the circuit when temperature exceeds a set limit
Protects against overloads and overheating
Commonly used in motor protection applications
- Q2. What is an RDOL starter?
- Ans.
An RDOL starter is a type of reduced voltage starter used in electrical systems to reduce the starting current and torque of a motor.
RDOL stands for Reduced Direct Online starter.
It is used to start induction motors in a controlled manner.
RDOL starters reduce the voltage supplied to the motor during starting to limit the inrush current.
This helps in reducing mechanical stress on the motor and connected equipment.
