Line Fault Indicator (LFI)

PLC NETWORK  DIAGNOSTIC TOOLS  –A.K.A PLC CLEANERSince 2001, our technical partner has been dealing with both, the design of PLC communication modems, and their subsequent implementation. Due to this, these products incorporate procedures that provide information on the quality of the received signal, the state of the communication path, and other diagnostic variables such as phase monitoring (recognizing whether it is the phase to which the opposite modem is transmitting or whether it is signal received by crosstalk in the cable line).As part of the PLC Cleaner solution, these modems are used for communication on low-voltage distribution systems, they are able to detect even the “bottlenecks” of the communication channel and, subsequently, recommend how to remove them. The big advantage of this solution is that it does not matter what standard (G3-PLC, PRIME, OSGP, METERS AND MORE, IDIS…) is deployed in a given location and there is no need to manipulate already installed electricity meters.

PD Doctor brings precise and reliable diagnostics and online monitoring of isolation conditions at medium (and low) voltage lines and devices in transformer and switchboard stations.It increases the reliability of the power supply, as it detects the power line damage, and immediately identifies and reports operational states and anomalies. The system saves online data and plays the role of a black box, where it is possible to analyze the history of operational states, including incidents just right prior to the failure.Partial discharge online monitoring enables to observe of the degradation process of power lines and devices and indicates the necessity of intervention for better repair planning. PD Doctor allows to decrease actually necessary prophylactics costs by thousands of USD annually and lowers field visits.PD Doctor helps to protect every electrical device – generators, electric motors, transformers, cable lines, overhead cables, switchboards and switchgears. Online measuring significantly decreases costs of new devices installation, as it allows to use a technical lifetime of devices and lines maximally. They can thus be safely and reliably operated until the physical (and not only theoretical, and statistical) end of their lifetime.
