extremely urgent please, why a fuse is used before voltmeter but not with a ammeter connected to a CT(current transformer),thanks in anticipation.
4 10377We have drive feeding an output contactor for a 5000 hp motor @ 5kV application. The motor FLA is 629amps x 1.25% service factor = 786.25 amps The cable that we current have in place between the drive and the output contactor is 350kcmil- MV-105 (parallel cables). Per the NEC table 310.60 (C) (69). This show the cable ampacity is at 615 amps per cable for a rating of 1230 amps. We have derated the cable for the cable tray and the multiple cables application and our calculations show that after the correction factor factor we are at 922amps. 1230 amps x .75% correction factor factor = 922.5 amps. The customer is driving us to then use another safety factor of .25% off of the already derated cable. Can you please provide a longhand calculation for your solution on this application?
1 2215watt meter have 4 terminals what there name??? and what theses 4 terminals indicates ?? and why 2 terminals are short circuited??
1 6480what is the difference between single ratio, multiple core and multiple ratio, multiple core ? please explain.
NTPC,
1 2267why the 4 terminal are named as main, line, common, voltage (M, L, C, v) of a wattmeter?? why not its nameed as A,B,C,D??
