5-11 Voltage, Current Waveform and Harmonic Analyzer
Application:
May device power sources now use semiconductor control devices and
harmonics occur because of distorted voltage or current wave forms.
When harmonic components become too large, they can cause serious
accidents, such as transformer supplying seeming average loads are
overheating, neutral conductors in balanced circuit are overheating from
exceesing loads, circuit breakers are tripping for no apparent reason,
overheating the motor or burning out the reactor connected to the phase
advance capacitor. Please refer to software manual (CD-ROM) for waveform
and harmonic measurement.
