  • Chapter 5 : Power Meters
    EE 101 MEASUREMENT Power Meters / 1 CHAPTER 5 : POWER METERS 5.1 Power Meter Power meter is electric meter : and define as a meter for measuring the amount of electric power used in watt of any given circuit. Figure 5.1 : Power Meter 5.2 Principles of Analogue Wattmeter W P Figure 5.2 : Symbol of Power Meter The traditional analog wattmeter is an electrodynamics instrument. The device consists of a pair of fixed coils , known as current coils , and a movable coil known as the potential coil . The current coils connected in series with the circuit, while the potential coil is connected in parallel . Also, on analog wattmeters, the potential coil carries a needle that moves over a scale to indicate the measurement. A current flowing through the current coil generates an electromagnetic field around the coil. The strength of this field is proportional to the line current and in phase with it. The potential coil has, as a general rule, a high-value resistor connected in series with it to reduce the current that flows through it. The result of this arrangement is that on a dc circuit, the deflection of the needle is proportional to both the current and the voltage , thus conforming to the equation W=VA or P=VI . On an ac circuit the deflection is proportional to the average instantaneous product of voltage and current, thus measuring true power, and possibly (depending on load characteristics) showing a different reading to that obtained by simply multiplying the readings showing on a stand-alone voltmeter and a stand-alone ammeter in the same circuit.

  • What Is True-Rms?
    Left: Sinusoidal (sine) alternating current waves. Right: nonsinusoidal waves. What is true-rms? A true-rms device (rms = root mean square) is one of three tools that can measure alternating current (ac) or ac voltage: 1. True-rms digital multimeters (or clamp meter) 2. Average-responding digital multimeter (or clamp meter) 3. Oscilloscope Only the first two are commonly used, and both can accurately measure standard (pure ac) sinusoidal waveforms. Yet a true-rms meter is widely preferred because only it can accurately measure both sinusoidal and nonsinusoidal ac waveforms. See illustrations at the top of the page. Sinusoidal (sine) waves: Pure, without distortion, with symmetrical transitions between peaks and valleys. Nonsinusoidal waves: Waves with distorted, irregular patterns—spikes, pulse trains, squares, triangles, sawtooths and any other ragged or angular waves. As mentioned previously, rms = root mean square. Though its formula can be challenging to grasp, rms essentially calculates the equivalent direct current (dc) value of an ac waveform. More technically, it determines the “effective,” or dc heating value, of any ac wave shape. An average-responding meter uses averaging mathematical formulas to accurately measure pure sinusoidal waves. It can measure nonsinusoidal waves, but with uncertain accuracy. A more sophisticated true-rms meter can accurately measure both pure waves and the more complex nonsinusoidal waves. Waveforms can be distorted by nonlinear loads such as variable speed drives or computers. An averaging meter attempting to measure distorted waves can be up to 40% low or 10% high in its calculations. The need for true-rms meters has grown as the possibility of nonsinusoidal waves in circuits has greatly increased in recent years.

  • TA018 60 a AC/DC Current Clamp User's Guide
    AC/DC mA CURRENT CLAMP TA018 USER’S GUIDE CLAMP 300V CAT.II 60A INTRODUCTION The AC/DC mA Current Clamp is a transducer which will allow your multimeter to measure low electrical or/and elec- tronic current up to 60 amperes AC/DC, with a frequency response up to 20kHz. When measuring current with this clamp, there is no need to break a circuit or to disturb the insulation. The extended measurement jaws allow performing mea- surements in a narrow space. When measuring DC current, a simple operating push button is designed for zero adjustment. The clamp adaptor is applicable to leakage detec- tion or monitoring. APPLICATION PROCEDURES 1. Connect the BNC plug to the input of any oscilloscope or other measuring instrument with an input impedance of at least 10 kΩ. 2. Set the power switch from “ OFF” to the desired range, 1mV/10mA or 1mV/100mA position. The green LED will light to indicate that the clamp is switched on. 3. For current measurement below 2A, set the unit to 1mV/ 10mA range and set the oscilloscope to 200mV AC range for AC current measurements, or 200mV DC range for DC current measurements. If the measured current exceeds 2A, set the unit to 1mV/100mA range. 4. When perform DC current measurement, always push the zero adjustment button on the clamp until the oscilloscope reads zero. 5. Clamp the jaws around the current-carrying conductor and interpret the reading according to Step 3 above. 6. When 1mV/10mA range of clamp unit is selected, multiply the reading displayed on the oscilloscope by “10” to interpret the measured current value in mA.
