Distribution Networks (6-50kV) LineTroll 110EμR is a conductor mounted indicator for detection of PtG and PtP faults in overhead line networks.LineTroll 110EμR is a conductor mounted indicator for detection of PtG and PtP faults in overhead line networks.The indicator is powered by replaceable long-life lithium batteries which have a life expectancy of 10-12 years. It provides a 360 degree visibility for indication both for transient faults and permanent faults.
The indicator unit has the same detetion / sensing principles as the local indicator LineTroll 110Eμ. The difference is that it is equipped with a built-in 2.4GHZ radio device which can communicate with a receiver located in a cabinet on the pole.
Nortroll offers several types of receivers («Collectors»).
– ComTroll 115C has a general digital interface which can be connected to any NorTroll- or third parties RTU for communication to a SCADA system.
– ComTroll R110CQ is a battery operated pole mounted collector with built-in GSM modem (SMS/GPRS) for communication to NetTroll monitoring system or NetTroll SCADA Gateway.
– ComTroll 118C is a collector which communicates with the indicators by 2.4GHz radio link, and in the other end communicates on a RS485 serial link on the Modbus protocol. It can be connected to NorTroll- or third parties RTU for communication to a SCADA system.
