The second is that problems discovered during this process are usually much less costly to repair than those discovered during a critical situation. Q: We are completing a project that includes a new generator for our hospital. Better yet visit us every weekday for news, insights and advice for healthcare facilities professionals. Health care facilities managers must consider a number of factors when it comes to installing and using emergency power generators. This not only gives you the benefits of genset redundancy, but now you have fuel redundancy as well.
A written record of generator inspections, tests, exercising, operation and repairs must be maintained on the premises and be available for review by the fire inspector on request. If one or more of the legs drops below 105 volts at full load, there is a problem and the test is considered failed. Our generators have been thoroughly inspected, serviced, and verified, which ensures that you will be buying a quality generator that you can depend on. Clifford Power Systems can help in designing the proper planned maintenance program for your standby generator system, and our team of factory trained technicians will make sure your planned maintenance will be carried out professionally and any issues discovered will be brought to your attention promptly, ensuring you are prepared for the next interruption in utility power. Before 2007, the answer was no.
We also perform breaker testing, arc flash analysis and training, and transfer switch services. Typically, Level 1 is needed for health care or mission critical facilities only. But load bank testing is much more than that, and one of the most important reasons for performing load bank testing has to do with the problem of as a result of light loading. Our customers also have the ability to add different size generator sets to expand their system as their facilities grow. To carry out the testing process, the load banks should be supplied with quality rated cables to facilitate effective charge transfer.
An actual power outage event that operates the generator for 4 continuous hours at a load capacity of at least 30% would qualify the generator as meeting this load test, but it would have to be documented. Changes in testing include a requirement for testing after any repair or replacement, including battery replacement. Click here to see our comprehensive list of load banks, transformers, switchgear, power quality monitoring systems, corona detection devices and every other tool you need to ensure optimal performance of critical power systems. In effect, the first 30 minutes at 25 percent was dropped. The load can come from building load, but that may cause business interruptions when transferring from utility to generator.
Not only will you follow the law, prevent potential lawsuits, and maintain a safe working environment, but you could even save the lives of those in the hospital. Cogeneration can provide system efficiencies in the 85 to 90 percent range. It is very important that each test method be fully understood by all staff through appropriate notification and that the consequences of each method if something fails to function be weighed carefully. The equipment manufacturer may have additional maintenance requirements that will likely include monthly, quarterly, semi-annual and annual inspections and checks. The basic process features a few commonly understood steps. In addition to load tests, we also conduct more involved testing and our famed 31 point inspection process.
One set should be kept in a secure, convenient location near the equipment. One has to always consider the possibility that failure of the disconnecting means or some other unexpected contingency might make it difficult or impossible to restore normal power. Most generator systems are installed and then put into automatic mode. If you follow the testing and maintenance guidelines listed above, there should be no cause for concern here. Hospitals can test generators during periods of low clinical activity as long as they realize that the stress on the generators will be less than during peak periods, he says. It is important to note that load bank test services are sometimes offered by suppliers of power protection equipment e.
The operators usually want surety that it will run when fully loaded and hence a load bank test is responsible for taking the power protection system into a test in a controlled environment. Also, if a natural gas connection is shut off, the generator can still run on full diesel, which makes for a win-win situation. Hence, this testing is carried out by experienced and skilled professionals outside normal working hours. Generator testing is a big deal these days: In interviews with Briefings on Hospital Safety, recently surveyed hospital safety managers nationwide say that Joint Commission representatives requested to see generator testing records. When the adoption of updated codes finally happens, there will be substantial changes affecting emergency power system management in health care facilities. The battery-maintenance requirements have more load test details stipulated, including required response to bad readings. They reference the crank and rest cycles described in , which calls for 15 seconds of cranking, followed by 15 seconds of rest, repeated three times.
However, there is ongoing discussion to determine which loads should be served by the emergency systems, experts agree. Refer to the standard for more specific changes regarding design and operational parameters such as room and equipment temperatures, air flow, batteries, lightning protection, distribution and protection from hazards. After repairs, the test is started again from the beginning. This can be compared to which require consistent maintenance practices to ensure that in the case of dire they are working properly. In addition, because many of the installed generator systems that utilize a diesel engine present another challenge. If your hospital backup generators are only sized to supply your most critical functions, you will likely have issues handling this crowd of people. Another change is in the minimum required amount of fuel in seismic-risk areas.
