1. REASON FOR PURCHASING
At first glance, this may seem like a simple factor to address, especially when it comes to legally required generators. Whether the generator is needed for demand response programs, limited operation or powering an entire building, initially identifying the intent of the generator system is important before making a purchase. Identifying emergency loads what you expect out of your generator system will have a major influence on overall design and product selection
Part of the generator sizing process also includes the identification of the application’s peak load
requirements. For standby applications, the load target range is 60 to 80 percent. Under-sizing a generator does not help the life of the generator, and can actually lead to engine damage; this pertains to diesel engines in particular. Temperatures and fuel delivery requirements should also be kept in mind. A properly sized generator will provide an end user optimal product performance. Being able to account for concurrent and non-concurrent loads, as well as natural load sequencing, is imperative during the sizing process. Keeping up with ever-changing load profiles of different manufacturers can be a daunting task. When using sizing and specification tools, use a
program that is easily updated to ensure these changes are always taken into account.
Indoor and outdoor installations are both impacted by factors such as weather patterns and ease of access for service. While indoor systems are often considered more reliable, engineering considerations such as airflow, heat rejection, fuel delivery and equipment
access can influence a generator’s performance. The effects of these factors are greatly reduced when a generator is installed in an outdoor setting.
Yearly inspections and routine servicing are required for standby generators with less than 250 hours of annual run time. While filters and oil should be changed on a yearly basis, cranking batteries commonly need to be replaced every two to three years. Additional items, such as belts, hoses and coolant should be inspected and tested annually; replacements for these items are typically required every four to six years.
As the digital world continues to grow, the demand for accessible data updates has increased significantly. By developing innovative system monitoring technologies, select manufacturers are helping to ensure end users have up-to-the-minute access to information detailing the state of their industrial power applications, which helps field technicians complete product maintenance and servicing procedures more efficiently than ever before. While it is difficult to gather information on standby generators with limited run time, predictive monitoring is also becoming more
popular for UPS applications.
