According to the technical requirements for the new generation of integrated equipment in intelligent substations

a high voltage switch integrated monitoring device based on Power PC processor was designed. This device integrates the functions of the individual mechanism monitoring IED

measuring IED

surge arrester monitoring IED and main monitoring IED to accomplish the comprehensive function of condition monitoring of high voltage switch and local diagnosis in one bay. Test and field operation showed that the device met the accuracy requirement

and reduced the number of bay monitoring devices in an interval. This integrated monitoring device may have good application prospect and promotion value.
