MD 9273 Leakage Clamp
Current Harmonics
N: harmonic component 2 ÷ 9
Measuring range
IhN < 10 % IRange
10 % IRange < IhN < 100 % IRange
N: harmonic component 10 ÷ 19
Measuring range
IhN < 10 % IRange
10 % IRange < IhN < 100 % IRange
IRange: Nominal clamp current (RMS)
IhN: measured current magnitude of N
N: harmonic component
Note: current harmonics are measured at voltages higher than 10% of the range or 0.3 A, whichever is higher.
Note: if Irange is in the 100 A current range, the accuracy of the current harmonics is indicative.
Voltage Harmonics
N: harmonic component 2 ÷ 9
Measuring range:
UhN < 3 % URange
3 % URange < UhN < 20 % URange
N: harmonic component 10 ÷ 19
Measuring range:
UhN < 3 % URange
3 % URange < UhN < 20 % URange
URange: Voltage range (RMS)
UhN: measured voltage of Nth harmonic component
N: harmonic component
