Survey responses from researchers advocate for a unified approach in managing high voltage failures during data collection in particle physics experiments. The feedback highlights the benefits of implementing a common procedure across all detectors. The behavior and settings of a typical high voltage channel (CAEN A1832P board) are detailed, including monitoring and automatic trip recovery capabilities.

Mail’s survey: appeal for general policy VF Patrizia: “Based on the running experience of NA48, I'm strongly in favor of a general policy of the experiment in treating possible HV failures during data taking”. Massimo: “I think it would be better to have a general policy of the experiment rather than a "personal mood" of each subdetector “ Rainer: “I agree with Massimo, that we should have a common procedure for the whole detector, not different ones for individual sub-detectors”
