Harmonic Filter Function (Only Available in the 30032A)
1. Filter Characteristic of the 30032A
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%.
<Reference Figure 1: Harmonic Filter Characteristic 1>
2. Filter Comparison (between the On and Off States)
This is the filter characteristic in the On and Off states.
<Reference Figure 2: Harmonic Filter Characteristic 2>
<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>

1. What is a Harmonic?
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.
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).
3. The 30032A Employs a Harmonic Filter
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.
