MONITORING OF ELECTRICAL TRANSFORMER STATIONS Build your network of MV/LV transformer stations for the long term Complete and upgradable Quick roll-out Compatible with any system

GridWatch: Solution for supervising LV installations A tailored solution based on integration of the Ulys MCM multichannel meter ANTICIPATE AGING OF THE TRANSFORMER AND INSTALLATIONS TRACE AND SECURE THE ENERGY FLOWS OPTIMIZE THE INSTALLATIONS AND NEW CONNECTIONS Optimization of scheduling and reduction of maintenance costs Reduction of technical and non-technical losses Evaluation of the available reserve or the effective overload on the feeders or transformers Station ventilation control Calculation of MV voltages and currents Detection of door opening or station movement Monitoring of hotspots...

GridWatch measuring unit Measurement of the load factor and transformer unbalance Measurement of the currents and power values of each LV feeder LV transformer main feeder MV/LV power transformer Monitoring of transformer surface temperature LV feeder “blown fuse” detection Measurement of station’s ambient temperature and humidity Flood detection station water level

Strengths Complete and upgradable GridWatch includes all the sensors for supervising the critical points in the MV/LV transformer station. Proposed in various versions, it adapts to the available space and budget for optimum implementation. It will be possible to add sensors to GridWatch as required in order to instrument the transformer and then extend the analysis to the electrical feeders of the transformer station. Quick roll-out To reduce unavailability of the transformer station when the system is commissioned, GridWatch has been designed for quick installation and roll-out: openable current...
