Hi, I was wondering if anyone could pass on some much needed help.
The local rugby club have just built a floodlit area to use for training on. It consists of 3 12m columns with 1 Philips 1000w metal halide floodlight on each column with running gear etc with in the columns.
The power comes from the above diesel 12.5kva 230v 50hz generator. When testing today all appeared fine but after about 2 minutes the generator shut down with a high voltage alarm which is set at 250v.
We fired it all back up again to monitor what was going on. starting current 18 amps after 1 minute this reduced to around 12 amps I also noticed the voltage dropped to 225v over the next minute I noticed the volts steadily increase all the way to 250v and tripping out the generator with the high voltage alarm setting.
I initially suspected the generator regulator was at fault but I tested it against 3 500w led lights and it works perfectly fine. I also tried each metal halide floodlight individually on the generator but the same outcome happened only difference was the increase in voltage happened a lot faster. Also the generator is brand new.
Any help or guidance would be hugely appreciated.
Thanks
Dan
