Grounds on Cap Banks
... This is why we have ungrounded caps on the 23 and 25kV systems as even though they are grounded at their source there is a good chance of neutral pull during a fault. This is recognized by the surge arresters we use What about systems such as the 46kV where we ground cap banks but don’t carry the 46 ...
