What is a Harmonic? Waveform Image Harmonic refers to sinusoidal quantity having a frequency that is an integral multiple of the fundamental frequency (for example, the commercial frequency). When a harmonic is superimposed on the fundamental frequency, the waveform is distorted. Fundamental frequency 2. Why is it Necessary to Accurately Measure the Leakage Current of the Fundamental Frequency (Commercial Frequency)? One problem when measuring the leakage current to check the isolation of electrical circuits in power distribution equipment is that the electrical isolation cannot be correctly understood due to the influence of a harmonic current. That is, the leakage current flowing from the electrical circuit to ground is very small so that, in order to check the isolation of electrical circuits by means of the leakage current, it is necessary to remove the harmonic component of the leak current and measure only the current of the fundamental frequency (commercial frequency). Distorted waveform Harmonic *Waveforms obtained when measuring a distribution board of a Yokogawa Meters & Instruments 3. The 30032A Employs a Harmonic Filter Corporation office Conventional leakage clamp-on testers could not sufficiently remove harmonic current components so measured leakage current values were often larger than the specified value due to the influence of a harmonic current. In this case, retesting with an insulation tester was required, resulting in increased effort and cost for the test. Under these circumstances, Yokogawa Meters & Instruments Corporation has developed the leakage clamp-on tester 30032A, which employs a high-performance harmonic filter that can accurately measure just the fundamental frequency component of the leakage current. Characteristics of Harmonic Filter 1. Filter Characteristic of the 30032A 2. Filter Comparison (between the On and Off States) When the frequency is more than 60 Hz, the sharp filter removes the harmonic component, leaving the fundamental frequency. For example, the level of 100 Hz is attenated to approx. 1%. This is the filter characteristic in the On and Off states. <Reference Figure 1: Harmonic Filter Characteristic 1> <Reference> When the filter is in the On or Off state Amplitude ratios in the range between the fundamental frequency and the third frequency <Fundamental frequency: 60 Hz> Amplitude ratio [dB] 10 Second harmonic amplitude ratio Fundamental frequency at 50 Hz Amplitude ratio at 100 Hz: -41 dB (average) Fundamental frequency at 60 Hz Amplitude ratio at 120 Hz: -56 dB (average) 0 -10 -20 -30 -40 Filter state Harmonic On Off Fundamental 0 dB 0 dB Second Third -56 dB -1.3 dB -80 dB or more -6.7 dB Figure 2: Harmonic Filter Characteristic 2 Amplitude ratio [dB] Figure 1: Harmonic Filter Characteristic 1 <Reference Figure 2: Harmonic Filter Characteristic 2> Harmonic frequency Fundamental frequency: 50 Hz 60 Hz -50 -60 -70 -80 40 60 80 100 120 140 160 10 0 -10 -20 -30 -40 Comparison between the ON and OFF states Fundamental frequency: 60 Hz Difference: approx. -50 dB at 120 Hz -50 -60 -70 Filter ON Filter OFF -80 10 180 100 Freq[Hz] 1,000 Freq[Hz] Measurement Example : Measurement location of leakage current A: Measurement of the grounding wire for the transformer class B grounding work B: Measurement of the electrical circuit C: Measurement of the grounding wire of electrical equipment Measurement method of leakage current (1) 3-phase 4-wire electrical circuit Load device (2) Single-phase 3-wire electrical circuit B B B C IG E1 B A A IG E2 Example of load measurement with the CL Series E1 In the case of load current Current Load device Current *Be careful of the polarity in the case of direct current. 1 Load device Leakage Clamp-on Testers 30032A 30031A AC Leakage AC Leakage 40 40 AC/3mA~60A AC/3mA~60A Filter Can measure leakage AC currents of 1mA Filter function can cut off harmonics-currents components from 2nd order Filter function select on or off Can measure leakage AC currents of 1mA Standard AC Leakage model AC current measurement AC current measurement Range 3mA 30mA 30A 60A Accuracy: (% of reading + digits) Accuracy: (% of reading + digits) Filter function OFF Resolution 0.001mA 0.01mA 0.01A 0.1A Accuracy 0.010 I 32.70mA: 1.0%+5 0.05 I 50.0A:1.0%+5 50.0 I 60.6A:5.0%+5 Maximum Allowable Current 3.270mA 32.70mA 32.70A 60.6A Range 3mA 30mA 30A 60A 3mA 30mA 30A 60A Resolution 0.001mA 0.01mA 0.01A 0.1A Accuracy 0.010 I 32.70mA: 1.5%+5 0.05 I 50.0A:1.5%+5 50.0 I 60.6A:5.5%+5 0.001mA 0.01mA 0.01A 0.1A Accuracy 0.010 I 32.70mA: 1.0%+5 0.05 I 50.0A:1.0%+5 50.0 I 60.6A:5.0%+5 Maximum Allowable Current 3.270mA 32.70mA 32.70A 60.6A Zero correction 3 mA range: Displays 0.000 mA (zero) when 0.010 mA < I 30 A range: Displays 0.00 A (zero) when 0.05 A < I Filter function ON Range Resolution Maximum Allowable Current 3.270mA 32.70mA 32.70A 60.6A General Specifications Parameter Method Display Specification Mean-value detection and rms-value calibration LCD (Digital reading 3200 counts) Bar graph (32 segments) Range swiching Range selection Auto or Manual Data Hold On all Range Operating temperature and humidity 0 to 50C, 80% RH or less (no condensation) Temperature coefficient Following values must be added in the temperature range of either 0 to 18C or 28 to 50C 0 I 50.0A: (0.08% of reading/C + 0.5 digits/C) 50.0 < I 60.6A: (0.3% of reading/C + 0.5 digits/ C) 0.0005%typical value (in terms of the magnitude of Effect of external magnetic fields: current in adjacent wires) Conforms EN 61010-1, EN 61010-2-032 Safety standards CAT.
