If the cold Load pickup feature has been programmed in (settings applied) is this function active in both local and remote conditions?
A. Yes cold Load pickup is active in both local and remote conditions. This is because the cold load pickup featured is intended for those applications where the start up currents of a system, which occur when the GVR are closed, might cause normal protection sequence to trip. Therefore it operates on closing of the GVR and not the method used to initiate the close. Refer to the GVR / Polarr Installation, operation and maintenance manual for further details. Q. As the GVR is a sealed pressure system does it leak SF6 gas? A. Yes, a very small amount of SF6 gas per annum. All GVRs are tested to BSEN 60694-15 this standard sets the leak rate per year at 1%, however the GVR tanks have a maximum leak rate of 0.64% per year which, as you can see is under the standard set by BSEN 60694-15.
