Abstract: A system and method of quantifying voltage anomalies may be used to quantify low frequency voltage transients such as the type caused by power factor correction (PFC) or similar events. The system and method of quantifying voltage anomalies receives sampled voltage data values and computes ideal sine wave data values. The system and method of quantifying voltage anomalies may also compute difference data values representing a difference between the received voltage data and the ideal sine wave and may compute score data values such as non-linear score values representing the difference data values relative to a peak voltage value or RMS voltage value.

Abstract: The power and environmental condition monitoring system monitors the quality of power provided to a site as well as other environmental conditions that might affect the operation of electronic equipment at the site. The system detects and records power events, such as spikes, sags, surges, and other transients, records power conditions, such as voltage level, RMS volts, phase differential, A/C frequency, current, and impedance, and records environmental conditions, such as temperature, vibration, and humidity. The system includes an analog signal receiver that receives analog signals from measurement devices and converts the analog signals into digital signal data. At least some of the channels on the analog boards are high frequency channels capable of receiving and converting high frequency voltage event signals. The system also includes a digital signal processor (DSP) for reading the raw digital signal data from the analog signal receiver and for processing the raw digital signal data.
