There are three main types of high circuit breakers in high line: air circuit breakers, oil circuit breakers, and SF6 circuit breakers.
Air circuit breakers use air as the arc extinguishing medium.
Oil circuit breakers use oil as the arc extinguishing medium.
SF6 circuit breakers use sulfur hexafluoride gas as the arc extinguishing medium.
To find current in three phase, use the formula: Current = Power / (sqrt(3) * Voltage * Power Factor)
Calculate the total power in the three phase system
Determine the line-to-line voltage
Find the power factor of the system
Use the formula: Current = Power / (sqrt(3) * Voltage * Power Factor)
