I just tested a residence where a bulb died and tripped the breaker. The service is 130 volts to ground. I read a thread here about using 130 volt bulbs to lengthen bulb life, and how using 120 volt bulbs on a 130 volt system will shorten their life.

My questions are, isn't this voltage a bit high, can the POCO adjust it, or can I install a transformer to adjust it? The service is 200 amp.
