Line PT is connected in the incomer (line) to detect the
voltage of the incomer whereas bus PT is connected in the
bus, 1 before the bus coupler and another after bus
coupler, to detect voltage in the bus.

The main purpose of both of them is to sense the voltage so
that the breaker can get enough information to operate..

Answer / maloy

line pt is connected in incomer where the bus pt is connectd in the main bus bar though both funtioning the same for measurement & protection

Answer / muhammad abid ali shah

Line PT is used to measured the voltage and also used for voltage protection means that under voltage or over voltage and the bus PT is used for metering and measure the voltage of bus bar voltage.

Please clarify, 1. Is it required to lay two runs of GI wire along with Armoured LT cable if it is laid between one big mains (63Amps TPN SDF) to small main (32A TPN SDF) with proper glanding termination? 2. If the armoured cable with proper glanding is laid from DB to CNC machine, is it required to run two runs of body earthing to the Machine from DB? 3.If the armoured cable with proper glanding is laid from Substation to Hangar, distance is approx. 100 mtrs, is it required to do earthing at shop area though the primary termination at substation is earthed through gland.
