Verified Answer
For below 400 KV systems, the circuit breaker is designed to withstand...
Rated voltage of circuit breaker:
- For below 400 kV systems, the circuit breaker is designed to withstand 10% above the normal system voltage.
- For an above or equal to 400 kV system, the insulation of the circuit breaker should be capable of withstanding 5% above the normal system voltage.
- The voltage rating of the circuit breaker is normally from 1.05 to 1.10 times more than the normal operating voltage.
- this is because during no load or small loads condition voltage level of the power system is allowed to rise up to the highest voltage rating of the system

Design of Circuit Breaker for Below 400 KV Systems
The circuit breaker used in below 400 KV systems is designed to withstand a certain percentage above the normal system voltage to ensure reliable operation and safety.
Answer Explanation
Correct Answer: Option 'A' - 10%
Explanation:
- The circuit breaker is designed to withstand a voltage level that is 10% above the normal system voltage.
- This additional capacity allows the circuit breaker to handle voltage fluctuations and transient overvoltages that may occur during normal operation.
- By designing the circuit breaker with a 10% margin above the normal system voltage, it can effectively protect the system and equipment from damage.
- This design feature is crucial in ensuring the reliability and longevity of the electrical system.
Therefore, for below 400 KV systems, the circuit breaker is designed to withstand 10% above the normal system voltage to maintain system integrity and protection.
The circuit breaker used in below 400 KV systems is designed to withstand a certain percentage above the normal system voltage to ensure reliable operation and safety.
