HiMON® makes the availability of cable systems comparable to that of overhead lines.

Product and service overview

Methods

RT-TF Analysis and synthesis of all cable sections

Periodic modelling of a cable section between two sensor units. Injection of small impulses into the cable in order to determine the transfer function of the cable section.

TruePD Measurement and filtering of real signals

Localization and determination of detected partial discharges at the location of the fault under consideration of the actual cable transfer function. Classification and characterization of the events with AI algorithms.

Cable breakdown

A break down within the cable insulation causes a high power transient impulse that leads to travelling waves moving in both directions of the fault location.

Fault localization

Determining the location of the fault under consideration of the measured transit time of the travelling waves.

Expert system

The HiMON® Intelligence Cluster is a cloud-based solution for evaluating the transmitted measured values. The extensive knowledge of our experts is used to continuously improve stochastic algorithms and artificial intelligence methods.
