In this session it contains 10 questions about power generation. 1. Wattmeter cannot be designed on the principle of electrostatic instrument thermocouple instrument moving iron instrument electrodynamic instrument 2. Which of the following is measured by using a vector voltmeter? Amplifier gain and phase shift Filler transfer functions Complex insersion loss All of the above 3. Standard resistor is made from platinum maganin silver nichrome 4. An instrument transformer is used to extend the range of induction instrument electrostatic instrument moving coil instrument any of the above 5. In an energymeter braking torque is produced to brake the instrument safe guard it against creep bring energy meter to stand still maintain steady speed and equal to driving torque 6. The rectifier instrument is not free from temperature error wave shape error frequency error all of the above 7. A multirange instrument has multiple shunt or series resistances inside the meter multicoii arrangement variable turns of coil multi range meters inside the measurement system 8. Commonly used standard capacitor is spherical type concentric cylindrical type electrostatic type multilayer parallel plate type 9. Two holes in the disc of energymeter are drilled at the opposite sides of the spindle to improve its ventilation eliminate creeping at no load increase its deflecting torque increase its braking tcrque 10. Various adjustments in an energy meter include light load or friction lag and creep overload and voltage compensation temperature compensation all of the above Time's up Share your love Facebook Twitter Pinterest Linkedin
