We have a retrofit 15 kV generator breaker with a GSU side TRV capacitor rated 200 nF. After installation we discovered that the capacitor nameplate indicates that the capacitor does NOT have an internal discharge resistor. This is the first time we've seen a medium voltage capacitor that did not include self discharge (i.e. <50 V within 5 minutes) however, we are struggling to find a requirement for it. The NEC specifically excludes surge capacitors that are part of an apparatus "conforming to the requirements of the apparatus". The breaker supplier is balking at the requirement and, though it is standard practice to ground MV systems before they are touched, it does not seem like this is acceptable when there are no automatic means of grounding or installed grounding switches. Is there a requirement we are missing? The supplier will not correct this if we cannot quote a specific requirement.
