Jithish_George Posted January 22, 2019 Report Share Posted January 22, 2019 My team has decided to make a prototype of an "Advanced" SPD by incorporating an electronic circuit which shows notifications and an additional circuit which shows earth faults if any in a circuit. As we were planning to use MOVs with Thermal cut-off, the notification incorporation is not a big deal. But the problem is that, there is only 20kA Imax for the proposed model of EPCOS and we require models with more than 40kA which is not available in the MOVs with Thermal cut-off so we have decided to use normal MOVs of that capacity for which there is no notification/monitor lead. Please propose any alternative or a better idea to put this things together. Also we are trying to use GD tube/Spark Gaps in the higher models along with MOVs for which the notification is again a concern. valuable suggestions please!!!
