If you have experience with emergency generators for backup power, you may be aware that a “no-start” failure is one of the most common reasons for generator system failures. While “no-start” failures are often attributed to failed batteries, the battery charger is sometimes the silent culprit. This article looks at battery charger technologies, and some features that can increase the reliability of your emergency generator system.
There are several topics that should be considered before selecting and specifying a diesel fuel transfer pump. The basic points are sufficient flow rate, electrical power requirements, and suitable environmental protection. But what about system pressure regulation, control requirements, alarm monitoring and failure detection? Read on for a step-by-step on how to properly select and specify a fuel transfer pump.
The failure to automatically transfer a building’s electrical load to an emergency generator is a nerve-racking scenario that any facility manager would prefer to avoid. For this reason, automatic transfer switches (ATS) are considered one of the most critical components of an emergency power system. This article discusses the use of “open vs. enclosed” contacts in transfer switches, and also alerts you to a basic transfer switch design feature that may not be in your current specifications, with possible negative consequences for the facility’s owner.
Mission-critical facilities are growing steadily as a niche market segment for MEP design firms. No longer limited to financial data processing or telecommunications, these critical facilities are now in high demand for a new breed of “in the cloud” data storage and “big data” applications. Whatever functions they support, one thing remains constant – these facilities have an absolute need for reliable electric power. A recent study found that the average cost for a power outage at a data center exceeds $500,000. So, how can these facilities improve the reliability of their electric power system? Testing is one key, and there is one device in particular that makes testing procedures safe and efficient.
