Score: 4.9/5 (57 votes)
Definition: An integrating instrument is an analog device which is used to measure the total energy supplied by the circuit in a given amount of time and is independent of total energy consumed. Example: The best example of integrating systems is the watt-hour meter.
Which instrument is an example of an integrating instrument?
The energy meter, watt-hour meter and the energy meter are the examples of integrating instrument.
Which of the following is an integrating instruments?
Integrating instruments totalize events over a specified period of time. The summation, which they give is the product of time and electrical quantity. Ampere hour and watt hour (energy) meters are examples of this category.
Which one below is an example of integrating instrument?
Example: Ampere-hour meter, Household energy meter, kilovolt ampere-hour meter.
How does an integrating instrument differ from an indicating instrument?
Indicating Instrument – The instrument which indicates the magnitude of the measured quantity is known as the indicating instrument. ... Integrating Instrument – The instrument which measures the total energy supplied at a particular interval of time is known as the integrating instrument.
1. Indicating, Recording and Integrating Instruments | Absolute & Secondary Instruments
What are the 4 types of instruments?
Each instrument has unique characteristics, such as the different ways they produce a sound, the materials used to create them, and their overall appearance. These characteristics ultimately divide instruments into four families: woodwinds, brass, percussion, and strings.
Which of the following is not an integrating instrument?
Voltmeter is not an integrating type of instrument.
Are integrating instruments *?
Definition: The integrating instrument measures the total energy supplied by the circuit in a given interval of time. It is independent of the rate at which the total energy consumed. The watt hour meter is the example of integrating instruments.
What is a Megger used to measure?
The Megger insulation tester is a small, portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. For good insulation, the resistance usually reads in the megohm range.
Which is an absolute instrument?
Absolute instruments are defined as the instruments that give deflections in terms of physical constants and not measurable on a graduated scale. The value of the electrical quantity to be measured are given by these instruments.
Are potentiometer may be used for?
The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name. Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment.
What are recording instruments?
Definition: The recording instrument is defined as the instrument which records the continuous variation of the magnitude of an electrical quantity for a particular period. ... The voltmeter, thermoscope, ECG machine, galvanometer recorder are the examples of the recording instrument.
What is electrostatic instrument?
Electrostatic instruments are usually used to measure AC or DC voltages that may include high-frequency voltages. They draw little power, and their readings are independent of frequency. Because electrostatic instruments are sensitive to external electrostatic fields, they are equipped with internal shielding.
What is an integrating meter?
[′int·ə‚grād·iŋ ′mēd·ər] (engineering) An instrument that totalizes electric energy or some other quantity consumed over a period of time.
What is indicating type instrument?
10. 1)Indicating: Indicating instruments are those which indicate the instantaneous value of the electrical quantity being measured, at the time at which it is being measured. Their indications are given by pointers moving over calibrated dials(scale), e.g. ammeters,voltmeters and wattmeters.
What type of instrument is energy meter?
Energy Meter or Watt-Hour Meter is an electrical instrument that measures the amount of electrical energy used by the consumers.
Why DC is used in Megger?
If we apply DC voltage then as we know Capacitor blocks the flow of DC, only leakage current due to imperfection of insulator will flow and hence the Resistance measured by Megger will actually represent Insulation Resistance. This is the reason, an Insulation Tester or Megger have DC voltage generator.
What is the difference between insulation tester and Megger?
An insulation tester performs the basic measuring function a megohmmeter does—measuring very high resistance values by sending a high voltage signal into the object being tested—and it often does much more; it usually performs more functions, including more complex testing and recording of measurements.
What is a mega tester?
A Megohmmeter or insulation resistance tester is a special type of ohmmeter used to measure the electrical resistance of insulators.
How are instrument transformers different from shunts and multipliers Mcq?
In instrument transformers, readings are independent of the values of R, L, and C. But in the case of shunts and multipliers, the readings depend on the values of circuit constants.
How do you read a wire instrument?
- Hot wire instrument works on the principle that the length of the wire increases because of the heating effect of the current flow through it.
- When the current is passed through the fine wire it gets heated up and expands.
- The sag of the wire is magnified, and the expansion is taken up by the spring.
What is an analogue ammeter?
Analog ammeters, also known as current meters, are metered instruments that measure current flow in amperes. Current levels are displayed on a dial, usually with a moving pointer or needle made of a soft iron. ... This type of ammeter is called a shunt.
What is Mi type voltmeter?
Definition: The instrument in which the moving iron is used for measuring the flow of current or voltage is known as the moving iron instrument. ... The magnetic field induces by the electromagnet whose strength depends on the magnitude of the current passes through it.
Which of the following types of instrument can be used for DC only?
Permanent Magnet Moving Coil (PMMC) is only used for DC measurements.
Which devices may be used for extending the range of the instrument?
- Switchboard is not used for extending the range of Instrument.
- There are four common devices used for the range extension of ammeter and voltmeter namely; multipliers, shunts, current transformer and potential transformer.
