Kirloskar Pneumatic Design Engineer Interview Questions and Answers

Q1. HOW TO CALCULATE CT CURRENT
Ans. 
CT current can be calculated by dividing the primary current by the turns ratio of the current transformer.
• CT current = Primary current / Turns ratio

• Primary current is the current flowing through the primary conductor

• Turns ratio is the ratio of the number of turns in the primary winding to the number of turns in the secondary winding

Q4. What is TCS AND MASTER TRIP REALY
Ans. 
TCS and Master Trip Relay are protective devices used in electrical systems to prevent damage during faults.
• TCS stands for Time Current Characteristic Relay, which operates based on the relationship between time and current to trip the circuit breaker during faults.

• Master Trip Relay is a relay that receives signals from various protective relays and initiates a trip signal to disconnect the circuit in case of a fault.
