Instrumentation – Power generation Quiz, part 5 Leave a Comment / By Sivaranjith / February 22, 2018 November 11, 2020 Welcome to your quiz . In this session it contains 10 questions about power generation. 1. 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 2. 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 3. The rectifier instrument is not free from temperature error wave shape error frequency error all of the above 4. 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 5. Standard resistor is made from platinum maganin silver nichrome 6. Wattmeter cannot be designed on the principle of electrostatic instrument thermocouple instrument moving iron instrument electrodynamic instrument 7. Various adjustments in an energy meter include light load or friction lag and creep overload and voltage compensation temperature compensation all of the above 8. 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 9. An instrument transformer is used to extend the range of induction instrument electrostatic instrument moving coil instrument any of the above 10. Commonly used standard capacitor is spherical type concentric cylindrical type electrostatic type multilayer parallel plate type Time's up
