The TMS-5041 is a lightweight easy to operate partial discharge monitoring system mainly designed for standalone operation with a simple interface to a third-party system or software. The TMS-5041 measures sequentially 4 Partial Discharge channels. The system has a 4-20mA analogue output per channel, one common alarm relay output and Modbus RTU interface for communication with the SCADA system or any third-party plant monitoring system. A Windows based Software is included to download actual partial discharge measurement results via the USB 2.0 interface. Built-in variable high and low pass filters and external gating channels allow the removal of noise from the measuring channel. Partial discharge results are shown as 8-bit phase resolved partial
discharge patterns offering 256 amplitude windows and 256 phase windows. For installation within a cubicle, the device is available in a 35mm DIN Rail mountable enclosure or for standalone installation, the system is in an IP65 Protected Wall mount Enclosure integrated suitable for outdoor installation. On special request, the TMS-5041 is also available in a 19“ enclosure. Operation and configuration can be done without any computer through the integrated true colour touch screen with a very high resolution of 480x272 pixel.
Partial discharge measurements are often acquired periodically in a defined interval of around 3 to 12 months based on the condition of the stator insulation. The TMS-6141 is a portable partial discharge analyser especially designed for this type of application. The light-weight system weighs less than 3.5kg and can be easily transported within the plant and also whenever measurements are performed in remote areas. The optional TMS-9441 Multiplexer extends the portable analyser to a 16-channel partial discharge acquisition system. The TMS-6141 is a portable extended partial discharge analyser offering simultaneous partial discharge measurement over 4 channels. The TMS-6141 is technically identical with the TMS-5141 monitoring system and also offers the same
noise rejection technologies as variable high and low pass filters, noise rejection through the gating channel as well as the noise rejection through the common signals available on the input channels. The very high resolution 9-bit phase resolved partial discharge patterns are the state-of-the-art partial discharge signal visualisation offering detailed information of any kind of partial discharge activity and allows to determine cross-relation of partial discharge activity between the channel / phases. The large build in true colour 5.7“ touch screen with a very high resolution of 640x480 pixels allows the device to be operated directly without the need of any connected computer. The system can be operated standalone or it can be remote controlled through the build in 100Mbit Ethernet interface with the Windows Based TMS-2141 Real-time partial discharge visualisation and control software. For temporary continuous monitoring, the TMS-6141 can also be connected to the TMS-2000 Database Server for automatic long-term data storage. When the TMS-6141 is used standalone without any computer multiple configurations can be stored within the device thereby keeping system configurations for multiple machines. Up to 100 recordings per configuration can be stored within the device and can further either be downloaded manually with the supplied software package or automatically into the TMS-2000 Database server if required.
The TMS-5141 is an online partial discharge monitoring system with extended functionalities. It measures simultaneously 4 partial discharge Channels, allowing enhanced partial discharge analysis as the system can distinguish automatically discharges between the channels (discharges between phases). The system has for each channel one 4-20mA and one alarm relay output and a Modbus RTU interface for communication with the SCADA system or a third party plant monitoring system. The System can be operated as standalone and can be connected to the optional TMS-2000 Database server for automatic data storage into an SQL based database. The System is available in 19" Rackmount, Panel-mount for the installation in a cubicle. For simple
installations, the system is available in an integrated wall-mount enclosure. The TMS-5141 accepts most partial discharge sensors available on the market such as classical partial discharge coupling capacitors or high frequency current transformers. The build in touch based true colour LCD display shows pd activity locally as well as the actual system status. Basic system settings can be changed locally, for extended system configuration the supplied TMS-2141 software package is used.
Whenever it is required to use more than the standard 4 partial discharge channels, the TMS-5441 is an extension of the TMS-5141 offering the same functionalities but with a built-in 4x4 multiplexer at the input. The TMS-5441 can acquire sequentially 4 channels simultaneously. Analog outputs and relay contacts are grouped together where on the Modbus RTU interface all data is available individually. The TMS-5441 is available in standard 19“ rack mount or as 19“ panel-mount enclosure.
All TMS-Series devices offer variable high and low pass filters and an additional noise cancelling channel (gating) to reject or suppress external noises which might influence the partial discharge measurement. The extended TMS Devices including the TMS-6141 portable acquisition system offer additional TR gating which is a rejection of signal common on all measuring channels.
