Hi,
I am facing a disturbing problem here in 132 MW power plant. Maximum ambient temperature is +45C and humidity is about 55% to 70% and PLC pannels are in Engine room, some times engines trip with out any reason/alarm and restarted again, I feel the behaviour of the PLC power supply is not correct. If any of you have such experience please tell me the remedy.
Also there are about 117 instruments (sensors) such as thermocoples, PT-100s, pressure transducers are installed on each engine and there are total 9 engines. If any one have some calculations of persentage instruments malfuntions allowed with PLC please urgently send it to me. I shall be thankful.
