State the effects of errors in dynamometer type wattmeter due to i) pc- inductance ii) pc- capacitance iii) mutual inductance iv) Connection. Explain construction & working of attraction type M.I. Induction type single phase energy meters measure electric energy in? The operation of a ramp type Digital Voltmeter is based on the principle of. Advantages:  1) In case of digital volt meter the output signals is available in the form of discrete numerical. The voltage regulation in magnetic amplifier type voltage regulator is effected by? The ramp type DVM (single slope) is very simple yet has several drawbacks. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. It operates with large positive gate voltage only. Dual slope DVM: SAR type DVM: 1 It is highly accurate: It is moderately accurate: 2 Cost is high: It is inexpensive: 3 Two comparator is used: One comparator is used: 4 Poor resolution: Good resolution: 5 Slow speed: High speed: 6 Less Error: More error: answered Sep 4, … Working Principle of Wattmeter: It consists of two stationary coils, called current coils and one moving coil, called voltage or potential coil. (i) Application of PVC paper : 1. Principle: When sound pressure moves the diapharam in, the capacitance increases, and when it moves out, the capacitance decreases. This clever Analog-to-Digital Converter (ADC) has been at the heart of the Digital Volt Meter (DVM) for decades. The number of insulator discs (each rated 11 kV) required in a suspension type insulator string, The number of insulator discs (each rated 11 kV) required in a suspension type insulator string of 220 kV line is, The number of insulator discs (each rated 11kV) required in a suspension type insulator string of 220 kV line is 16, Cylindrical type transformer has:  (A) Single magnetic circuit (B) Double magnetic circuit (C) All of the above (D) None of the above, Cylindrical type transformer has: Single magnetic circuit.
