Preventive Maintenance Options
DB Power, Inc. has prepared a proposal for a Preventive Maintenance program (PM) designed to include the equipment at your locations. DB Power‘s PM is designed to increase the useful life of installed power equipment and provide pre-emptive maintenance of critical power systems through provision of regular structured maintenance by trained personnel. PM is designed to improve system reliability by addressing power related issues before they cause system down-time as it has been proven that a lack of regular maintenance on critical Power equipment can cause service disruptions or delays that inevitably mean lost revenue. Many DB Power customers have found that PM provides a lower cost option than down-time and lost revenue with system outages. DB Power’s service personnel are trained to work on all types of AC&DC power equipment and battery backed systems. They are equipped with the latest technical know-how and equipment to be able to identify and solve wiring, equipment and Battery issues.
DB Power’s PM includes:
1. Suggested two scheduled visits per year. A primary and subsequent visit. The primary visit is designed to capture all information and measurements for a system. The subsequent visit is mainly a visual and physical inspection.
2. The scope of the preventive maintenance program is as follows:
1. Rectifier Plants, batteries, distributions systems, cabling, grounding and utility assessments are inclusive.
2. Each system will receive a visual and physical inspection.
3. Vacuuming and cleaning of parts and assemblies will also be performed as needed.
4. AC/DC voltage and current measurements will be performed and cataloged.
5. Batteries will undergo Digital Low Resistance Ohmmeter testing to determine the overall condition of the batteries.
6. Connection Hardware will be checked for proper implementation and torque values.
7. Thermal scans of the equipment/facility will be made. The Infrared scan will help identify problem areas that escape the naked eye.
8. Continuity tests, alarming verifications / correction, meter calibration and label verification will be performed where needed.
3. A comprehensive report will be provided in hardcopy to the client
1. Scheduling and additional services are available through the website.
4. Corrective action proposals will be automatically generated to address any areas of concern identified during the audit and PM.
Additionally, site audits can be performed on a one time basis to establish the exact quantity, make and model of equipment in your facilities, if you require further information on our site survey programs or system expansion capabilities, please contact us.
