UL 1973 covers energy storage for solar photovoltaics, wind turbine storage, and other stationary applications as well as for light electric rail applications. UL 1973 is evolving into UL 9540, a newer standard that covers related systems for storing energy from power sources or providing electricity to power conversion equipment, for example electrical

The timeout argument is passed to Popen.wait (). If the timeout expires, the child process will be killed and then waited for again. The TimeoutExpired exception will be re-raised after the child process has terminated. Edit2: Example code for you, save this to a file and execute it with Python 3.3, at least:

Another variation used by Xcel Energy is time delays on alarms such as an oil temperature alarm on the pulverizer oil system. At Pawnee Station, oil temperature is maintained through cooling water
