Zero Export + DG Synchronizer

One single ZED Advance can work both like Zero Export Device as well as DG Synchronizer.  That's mean it can stop any power export to GRID and save DG Set from reverse power feed from PV plant. Check the function description of ZED Advance as Zero Export and as DG Synchronizer.

For Power monitoring and terminating any power export (or reverse) to Grid and DG STE, ZED advance required two sets of Current transformer along with 10 core, 1.5 Sqmm Cable, on the incomer of both Grid power and DG STE for the load the measurement as shown in illustration. During commissioning of the ZED we set the sharing point of load on DG SET at 30% of DG capacity and 0% at Grid, to keep DG SET minimum 30% loaded. And compares these measurements with the adjustable set point of the controller. When Grid power is available ZED advance work as Zero Export Device and when Grid power is not available,  ZED advance work as DG synchronizer.
