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 Hydro Generators, Turbo Generators 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.

Online: The Expert TMS-5141 Partial Discharge Monitor works with Partial Discharge Sensors that are installed on a once-off basis during a scheduled maintenance window. Information is captured while the machine is connected to the power system during normal operation.
Continuous acquisition and monitoring: 4 channel simultaneous data acquisition ensures a complete collection of information is available to provide meaningful analysis and diagnostics.
Automatic data acquisition, storage, diagnostics, trending: This is a true standalone condition monitoring solution that does not require a separate computer or device.
Built in full colour touch display screen: View Partial Discharge analysis and configure monitoring alerts, alarms and parameters.
Intelligent filtering: Built in Noise Separation Technology using variable filters, gating and common mode rejection to differentiate ‘Noise’ from real Partial Discharge.

Intelligent analysis and diagnostics: 4 channel simultaneous data analysis ensures every individual Partial Discharge pulse between each channel is correlated and analysed to visually pinpoint the actual location and severity of the weak spot.
Integrated with SCADA and 3rd party monitoring systems: Built in Modbus RTU for SCADA and 3rd party monitoring system and USB2 for direct computer connection.
IEC – 60270 compliant: The Expert TMS-5141 is fully compliant with the IEC – 60270 standard for High Voltage Test Techniques, Partial Discharge Measurement.
Extendable: The Expert is a single solution that can be easily extended to include other monitoring techniques as required using our modular additions. These include Magnetic Flux, Shaft Voltage Current and Temperature. This provides a holistic view of the state of your Rotating Machines without the need to purchase individual solutions.
