At petrochemical refineries and natural gas plants, the process of producing oil and gas involves an array of complicated steps. Every part of the industrial process depends on a reliable supply of electrical power to keep the machinery in motion. Production downtime is costly and, in the case of natural gas plants, the entire production run can literally go up in flames. As a result, most large oil and gas facility personnel consider onsite generators as their primary power sources and grid connections as insurance policies. From this viewpoint, it's easy to see why these employees place great importance on the proper protection and monitoring of onsite generators.
