Answer / nagarjuna jaladi

yes,Gopal its right,but how is the speed of electricity is the speed of light? Please explain.

Answer / kaustubh

meter/secs.

Answer / sheikh

almost 186,000 miles per second same speed as light.

Answer / gopal manda

yes Nagarjuna,but it is only in case of DC.

Answer / somu0507

1- speed of light = 1/ [squire root of{(permeability of free space)X(permitivity of the free space)}]
2-speed of drift of charge in a conductor = Drift Velocity = (mobility of charge X Electric field applied across the conductor)=few Centimeters per second.
3-speed of effect of electricity in a conductor = speed of current and voltage wave in the conductor = 1/ [squire root of{(permeability of the conductor)X(permitivity of the conductor)}]

Answer / janmayjay

A group of machines (wind turbines) connected with 33KV feeder and each machines are having individual VCB. The 33KV feeder connected with 110KV/33KV substation. The 33KV feeder tripped by over current at Substation and fault recorded at Substation as OC-R&Y phase. Same time the group of machines VCB tripped by over voltage, the fault recorded voltage was above 66KV by numerical Under/Over voltage relay. While grid drop time, this much of voltage hike is possible?
