Curtis Engine offers a wide range of predictive and preventative maintenance services to assist you in identifying problems before they shut you down. As part of our predictive maintenance services, we provide testing programs designed to keep our client’s emergency power supply systems ready when they are needed most. In general, we follow the manufacturer’s recommendations for testing but we also consider NETA, NFPA, and NEMA testing guidelines. With each testing program, test results are provided, along with any recommendations for repairs, and added to the service history for your equipment.
We can develop a regular testing program using our proven test procedures, performed by a qualified technician, to give you confidence in the whole system – from the fuel tank through the transfer switch – and keep your facility in compliance with NFPA and JCAHO regulations.
Load bank testing confirms the emergency power supply system’s ability to run up to its rated kW output and stay there without overheating and possibly shutting down during an emergency. During a load test, critical engine and generator parameters such as oil and fuel pressure, operating temperatures, voltage, frequency, amperage, and kW output are measured and recorded throughout the duration of the test. Typical load bank tests range between two and six hours.
Periodic load bank testing is an essential part of any good maintenance program. Load bank testing is not intrusive and during the test there is no interruption to the facility’s power supply.
Generator load bank testing serves two purposes:
Load bank testing reduces long-term costs by extending the life of engine components such as turbo-chargers and exhaust valves, as well as, increasing engine performance and efficiency while reducing pollution. It also provides peace of mind and insures compliance with NFPA 110* and JCAHO** standards for hospitals, nursing homes, computer data centers, and other critical facilities.
Curtis Engine has portable resistive load banks in multiple size ranges from 100kW up to 2MW and totaling over 3MW of load bank capacity. Our qualified technicians set up the equipment, perform the test procedures for the appropriate length of time, and provide a written report detailing the performance of the equipment being tested when complete.
Load bank testing is the only way to safely test your generator set’s ability to perform without risking a total loss of power or power quality by interrupting utility service. To schedule a load bank test or for more information, please call (800) 573-9200 or send an e-mail to service.
Curtis Engine’s fluid analysis program is a thorough, reliable and efficient way to see what is going on inside your engine. We use independent labs to analyze and test used fluid samples from your equipment for metal wear rate, contamination, and chemical breakdown. Our technical staff is trained to interpret the test results to detect potential problems before they become major failures.
Periodic oil and fluid analysis will allow you to develop a complete history of your engine and detect many problems before they cause major damage to your equipment. To learn more about our fluid analysis program, please call (800) 573-9200 or send an e-mail to service.
An infrared survey is a testing technique for monitoring the condition of electrical systems, as well as, the mechanical components on a generator set. It can safely and quickly detect a failing motor bearing, a loose electrical condition, and other “hot spots” before they fail or cause major equipment damage. Our trained technicians use an infrared camera to see infrared heat waves inside your equipment and measure their temperature. This data is then analyzed and the report along with our recommendations for any repairs is provided to you and added to the permanent service file for your equipment.
Equipment failure is almost always preceded with an increase in temperature. Regular surveys of the switchgear and electrical connections can identify sources of heat and resistance and potential points of failure. To schedule an infrared survey, please call (800) 573-9200 or send an e-mail to service.
We can provide an in-depth vibration analysis on all types of engines and generator sets. Our trained technicians take detailed measurements at specific points and evaluate the data to determine if there is any abnormal vibration due to mechanical problems.
We can also perform noise tests, exhaust gas emissions tests, leak tests, and insulation tests to make sure that your equipment is operating in the manner it was intended. For more information or to customize a testing program for your facility, please call (800) 573-9200 or send an e-mail to service.
NFPA 110, Standard for Emergency and Standby Power Supply Systems (EPSS) covers performance requirements for power systems providing an alternate source of electrical power in the event the primary power source fails. The standard addresses installation, maintenance, operation, and testing requirements for generators and automatic transfer switches (ATS).
NFPA 110 stipulates several different site tests for compliance. The following are some highlights from NFPA 110 for the maintenance and testing of emergency and standby power systems:
In addition to NFPA 110, the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) recommends that all automatic transfer switches are tested 12 times per year at 20 and 40 day intervals. The monthly test consists of electrically operating the transfer switch from the standard position to the alternate position and then a return to the standard position. Additionally, JCAHO requires that a written emergency plan be in place with clearly defined responsibilities and assignation of adequate staff, including multiple backup personnel. All such persons must be trained and their attendance should be taken into account by the EPSS supplier (i.e. Curtis Engine) when arranging such courses. The JCAHO maintenance requirements must conform to NFPA 110 for testing purposes, but in addition calls for monthly testing of generator and automatic transfer switches, as well as, the a four-hour test of the EPSS at least once every 36 months.

Whether your facility is legally required to comply with NFPA 110 or you just want adopt the best practices in the industry for maintaining, operating and testing your emergency and standby power systems, Curtis Engine can help you meet these requirements by providing:
