Petey:
I've seen a few similar over the years. All in BUD areas, failed line/neutral, temped out like your pics. And, yes, the estimated bills arrive every month. The POCO's have there own 'rules'!
In present time, this still happens, but...it's addressed quickly! Both POCO's (JCP&L & PSE&G). I must say..PSE&G addresses BUD issues within 12-24Hrs; OH (utility owned)is addressed by the trouble lineman when the emergency is called in.
