Abstract

Thanks to the implementation of the smart grid concept, the distribution network has seen a significant advancement in monitoring and control of the underground network.Among the past hurdles related to underground distribution, one can mention the limited options of available monitoring and communication technologies, namely the fiber optic based networks. Until recently, wireless communication was not reliable enough in underground environments and data transmission was a challenge. Innovative designs in manhole covers and new developments in communication technologies overcome this problem. Currently, no real time or on-line monitoring is being deployed in vaults or cable chambers with the exception of a few utilities.Recently, a second generation ofunderground sensing and monitoring system(USMS) with improved performance is capable to also measure the voltage and some environmental parameters such as: temperature, humidity, gas presence, water level, etc.The first generation of USMS was tested by IREQ and the results helped improve the design and performance of the second USMS generation.The tests, which were performed in IREQ’s laboratories at its facility in Varennes, QC, Canada, included:Voltage and current measurement accuracy and linearity of the second generation of USMSEfficiency of the Power harvester supplying the USMSUSMS compliance with IEEE 495 (short circuit)This paper introduces and discusses the second generation of an underground sensing and monitoring system and presents the results and the conclusions of the tests performed by IREQ
