Answer / parijaat

power load means the highest power that a plant can use,and
lighting load means the minimum power to maintain emergency
process running in a minimum load.Suppose a steel plant
requires 20 mw power to operate completely,then 17/18 mva
power is its power load,and 2-3mva load to operate emergency
processes in running condition,so it is its lighting load.

Answer / manimaran

The power load is nothing but bulk amount of power(huge
power) using in industry.lighting load means small amount
of power using particularly lighting load only.

in our all power plant have connected in grid and grid voltage and plant voltage is same, but as per as electrical concept the power will transmit from high potential to low potential but here altough same,then how power transmit from power plant to grid.

bit confused - am i correct in thinking that to determine line to line voltage in a star config 110v 3 phase 4 wire distribution system i would use a voltmeter? I have a circuit configured as an unbalanced load, consisting of three incandescent lamps (1x40w, 1x60w, 1x100w - all 110v rated)connected in a star configuration to a 110v 3 phase 4 wire distribution system. I want to find out what types of meters i would use to obtain: a) each line to line voltage b) the line to neutral voltage across each load c) current flowing in each line and load d) current flowing in the neutral conductor e) power supplied to the loads im assuming i would be using ammeters in series along each line and voltmeters in parallel across each line to neutral? Also how could i predict these meter readings before taking them and with which formulae? Any help would be greatly appreciated A.
