monitoring is not only an effective customer service strategy but also a way to
protect a utility's reputation for quality power and service.
CMHAI provides a method for monitoring the power quality by means of the current
waveform distortion. CMHAI provides a short-term 3-second average and a long-
term demand for TDD.
