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.

Q5. WHAT IS LSC 2A AND LSC 2B
Ans. 
LSC 2A and LSC 2B are standards for lighting in commercial and industrial buildings.
• LSC 2A and LSC 2B are part of the Lighting Power Density (LPD) requirements in building codes.

• LSC 2A is for commercial buildings while LSC 2B is for industrial buildings.

• They specify the maximum allowable power consumption for lighting per unit area in a building.

• For example, LSC 2A may require a maximum LPD of 0.9 watts per square foot
