Abstract
An assembly for monitoring or metering a plurality of electrical energy and power parameters wherein six current and six voltage stepped down transformers are associated with a drawout cradle in conjunction with a series of functional printed board circuit to achieve a conservation of components and a high degree of compactness in packaging. Accessibility for calibration and similar maintenance procedures is provided at the panel front of the apparatus and simple access to test outputs is provided at the front thereof. A connection plug arrangement is used to provide make before break switching with monitored power paths and for the purpose of providing additional calibration inputs at the forward portion of the assembly without resort to involved housing removal procedures. In one embodiment, a summing circuit is used in conjunction with Q and watt multiplier circuits to provide an analog var output in conjunction with pulse characterized watthour and Qhour outputs.
