3 Phase 4 Wire Meters
3-phase 4 wire meters (10/20, 20/50 A) are used for agricultural and industrial consumers. For loads up to 50 A, the meters are directly linked to the supply. For greater loads, it is preferable to gives CTs. They are rated for 415 V. In a 3-phase 4 wire meter, 3 pairs of coils of every type, i.e., potential coil and current coil are given for each of the three phases. Each of the 3 elements (coil pairs) of the meter produces equivalent torque, i.e., one-third of the total torque under all conditions of varying power factor.
Q. What the voltage gains in the FET amplifier? For common source Voltage gain=V o /V i = - µRd / Rd + rd where µ is the amplification factor,Rd the drain resistance a
Q. Effect of feedback on sensitivity to parameter changes? A good control system, in general, should be rather insensitive to parameter variations, while it is still able to fo
A single-phase, 50-kVA, 2400:240-V, 60-Hz distribution transformer has the following parameters: Resistance of the 2400-V winding R1 = 0.75 Resistance of the 240-V winding R2

Q. Explain the measurement of frequency in detail by using Wein's bridge. Sol. The Wein's bridge is presented here not only for its use as an AC bridge to measure frequency
Q. Introduction to power systems? Thomas A. Edison's work in 1878 on the electric light led to the concept of a centrally located power station with distributed electric power
Circuit Symbols for MOSFET A range of symbols are employed for the MOSFET. The basic design is usually a line for the channel along with the source and drain leaving it at rig
Q. What do you mean by Output Voltage Swing? Ideally this is equal to the difference between the two supply rail voltages, although in practice it is a few volts less.
