Axon Power Install 170kW EMMA Pro System Zero Export in McGarrity's Quarry

An EMMA Pro 170kW System limiting export to zero has been installed by Axon Power and Controls at McGarrity's Quarry in Tyrone. The system is preventing a G59 relay from tripping out by keeping the export at zero. The power is being used to heat a pre-heat tank that is pumped into a much larger 20000L tank that is now used to wash down the lorries that deliver the concrete products. The turbine is a Vestas 225 limited to 150kW output but can reach up to 170kW in gusts. The max output was observed during the commissioning of the system by Coolpower Products Engineers on site with the full load being deployed to prevent any export keeping the G59 engaged. The entire system is monitored via GPRS. This now allows the end client McGarrity Bros and the Agent Axon Power to view the turbine performance but also to view the site demand, import, export and amount of power being sent to the tank in a graphical format.

 

 

ELITE Control

The ELITE is the latest addition to the EMMA product family. While we consider it to be the Elite of power diversion and monitoring it is in fact EMMA's little sibling or as we call it EMMA lite.
