The OMS 800 system is designed to perform partial discharge (PD) after-installation testing and continuous monitoring of HV XLPE cable systems, either in underground tunnels or at buried cables. It can detect and locate partial discharges in cables and accessories (joints, terminations) simultaneously.
The OMS 800 monitoring system consists of sensors, acquisition units, data concentrators for pre-processing the data, as well as a system server and software components for modern data visualization and management. An inductive power supply (IPS) allows operating the acquisition units offside, e.g. in cable tunnel applications where copper wiring has to be avoided and voltage sources are not available.
