Effective monitoring for Wind Farms
Omniflex provide a packaged low cost communication solution for the capture of multiple digital alarm channels on Wind Farm installations, with remote transmission and monitoring
The systems include the supply of fully configured Teleterm M2 RTUs at the Wind Farm, to provide the alarm multiplexing action, and at the sub-station providing the de-multiplexing action The Teleterm M2 RTU at the wind farm captures up to 10 alarm inputs and, using either modem, radio or existing pilot cables, exchanges the data from the Wind Farm to the primary sub-station

Distributed alarm and event management system
The Maxilarm Alarm and Event Management System offers features such as sub-millisecond time stamping at source, integrated analogue logging and remote alarm fascias all to meet EEMUA 191 guidelines
Alarm Windows improve safety and reaction times
It is now an accepted fact that traditional window alarm fascias provide the fastest means of alarm notification to operators when facing avalanche conditions
At the sub-station, the second Teleterm M2 RTU is responsible for providing alarm inputs into the station alarm annunciator system for local annunciation (this can be an Omniflex Omni16c Alarm Annunciator system or any existing annunciator system) and also into a distributed monitoring system for onward transmission to a central control room.
Also at the Wind Farm locations, Omniflex provide their PT5K power supply units which can be used to provide power to the Teleterm M2 RTU units and modems.
These power supplies can then be monitored to ensure correct operation using the digital and analogue capability of the Teleterm M2 units.
To do this, digital inputs at the Wind Farm Teleterm RTU are assigned to monitor the supply voltages, whilst at the sub-station, analogue channels are used to operate a dual trip amplifier (Omniflex TTB trip amplifiers).
The trip levels are then set to indicate PSU failure and are used as two further alarm inputs into the sub-station alarm system.
Omniflex UK can provide this system as a complete solution for Wind Farm monitoring.
