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. The DSP processes the digital signal data by logging low frequency digital data and by detecting and logging high frequency event digital data. The high frequency event digital data is detected b…
