Q. Two balanced, three-phase, wye-connected loads are in parallel across a balanced three-phase supply. Load 1 draws a current of 20 A at 0.8 power factor leading, and load 2 draws a current of 30 A at 0.8 power factor lagging. For the combined load compute:
(a) The current taken from the supply and the supply power factor.
(b) The total real power in kW supplied by the source, if the supply voltage is 400 V.
LT Metering or Low Tension Metering The subsequent types of meters are generally used for LT consumers: Whole Current Meters i) Single phase meters ii) 3-phase
what is the difference between latch and flipflop
Q. Explain the working principle of an opto coupler? When it is necessary to block the voltage between one electronic circuit and another, and transfer the signal at the same t
Explain the effect of temperature on electrical conductivity of metals. As the temperature is increased, there is a greater thermal motion of atoms which decreases the regulari
Metering Techniques The techniques of metering could be categorized depending upon the voltage at which consumers are fed as: 1. LT (Low Tension) Metering, and 2. HT (Hi
Electrical power Power P in an electrical circuit is given by the product of potential difference V and current I. The unit of power is the watt, W.
1. Introduction : Theory: The voltage measured across a load follows the Ohm's law which says that the current passing through a conductor between two points is direct
