Expert TMS-5141 Partial Discharge Monitor

Description

The Expert TMS-5141 is a four channel partial discharge trending system with a true color LCD to display all the necessary information for the commissioning and surveillance of Medium Voltage and High Voltage Machines. The noise gating channel and variable LP Filter separates noise from actual partial discharge signals. The actual partial discharge levels for each individual channel (phase) are displayed on a bar graph and real time partial discharge activities are displayed in oscilloscope view and through a colorised phase resolved pattern.

The touch functionality of the LCD display allows the user to set alarms and parameters, and to visualise the partial discharge signals without the use of an additional computer. Optionally a computer can be connected through the built in Ethernet Interface to store permanently measured results. The Modbus RTU interface allows an easy integration into the exisiting SCADA/DCS system. Individual 4-20mA and relay outputs per channel are available.

This makes the Expert TMS-5141 the ideal partial discharge monitoring system for permanent installation with permanent data recording.
