Pittsburgh, PA, Aug. 9, 2006 — Industrial manufacturer Eaton Corp. introduced a new wireless communications system that allows utility workers to remotely monitor AC distribution network protectors, designed to alleviate the extra cost and risks associated with workers entering underground vaults.
Eaton’s new Cutler-Hammer branded NPView is a wireless web server that is placed inside the underground vault or above grade control room that can wirelessly transmit data from multiple Microprocessor Communications Variant (MPCV) relays underground to a wireless enabled laptop or hand held PocketPC. The remote monitoring system can monitor, calibrate, log data and control network protectors. The unit’s connection options provide local access up to 100 meters away from the module or with a cellular modem for infinite range ability, sparing utility workers the often dangerous task of entering vaults. It also allows maintenance crews to focus their attention on known power interruptions instead of the hours it can take to perform routine inspections underground.
Wireless monitoring reduces overall operating and maintenance expenses and provides users with more data to make performance-based maintenance decisions, thus increasing efficiency, said Eaton in a recent press release.
Up to twelve MPCVs can be connected to one NPView Web server. The relays can be daisy-chained for distances up to 2,400 meters without repeaters with simple twisted pair to the wireless module. The MPCV relay has had communication capability since 1996 and Eaton has an expansive list of existing hardwired communication customers.
In addition to the NPView offering, Eaton introduced another product for its MPCV communication family. The new Cutler-Hammer brand DNP Master INCOM Network Translator (DNPMINT) converts the native MPCV communications protocol to DNP 3.0 objects for existing Supervisory Control and Data Acquisition (SCADA) systems. MPCVs can be connected together to one DNPMINT, or multiple DNPMINTs can be connected together for a more expansive network.
