Daily Check as the Simplest Measure
Data centers can actually lose millions of dollars per hour due to the loss of power, and the importance of daily checks is also reflected in the daily checks being one of the industry standards such as the ISO9001 as well as National Power Supply Norms, which are also an industry standards. Such daily checks include fluid levels, the state of the battery, and the visible state of the components of the system. In the case of the fluids, it is necessary to have the engine oil, the fuel, and the cooling water at their appropriate levels with no leaks in the lines or joints. The starter battery must have the charge level, the fluid, and the voltage of the battery so that it can start at any time. No loose screw connections, and the consumed energy of the lights must be at their normal levels, and those lights must be functioning in the control panel. The case of one of the data centers in Africa shows that 80% of the failures in the starting of the generators are due to the lack of daily control of the fluid levels, as well as the battery aging.
Maintenance of Components in Depth on a Periodic Basis
The overall maintenance of the generator set is the most important factor that influences the service life of the generator set, as well as its long-term, trouble-free operation. The maintenance schedule must reflect the actual operating hours of the unit and the service/maintenance requirements from the brand. In regard to core components, according to the industry standard for maintenance, an oil filter, fuel filter, and air filter must be replaced within a year. However, for high standby activity data centers, this replacement cycle can be shortened. Replacement of the cooling water is to be performed monthly, and the PH is to be tested and kept within the bounds of 7.5 - 9 before and after replacement. The fan belt and charger belts are to be monitored for tightness on a monthly basis, and serviceable oil shall be added to all points of connection to provide for free movement of the related systems. The maintenance of all components must be recorded. This includes all replacement times, models of components, and all results/ data from tests conducted. This file shall be called the equipment health file and will be used in the future for both maintenance and in the analysis of faults.
Routine Load Testing for Operational Reliability
Testing the generators without a load will not accurately gauge their capability, and routine load testing becomes even more important to help decide if the unit will function properly in the event of a utility company controlled power failure. For most data center generators, maintenance requirements dictate that no-load testing is done each 15-day period with a time duration of 15 to 30 minutes to be followed by load testing for 15 to 60 minute time duration each 30-day period. While load testing is done, it is critical to monitor and gauge water temps, oil pressures, and power outputs in real time to ensure that all operational indicators are within their prescribed tolerances. A major data center located in East Asia/ Asia Pacific experienced a failure in their utility grid. Due to no load operations/ testing of their generator set, it could not provide the power that was required, and the data center experience a 2 hour outage. This case captures the essence of load testing and the capability it has to pinpoint operational deficiencies such as a poorly supplied fuel tank or a poorly connected circuit within the generator set.
The Importance of Digital Monitoring for Predictive Maintenance
As the data center industry develops towards greater intelligence, digital monitoring for predictive maintenance of generator sets becomes a focus of the industry. Professional generator monitoring systems can collect data on the operating status of the unit in real-time, such as temperature, vibration, voltage, and current. It is possible to use data analysis to predict potential failures. For instance, monitoring systems can identify and locate potential issues, such as a premature rise in temperature of the generator stator, and maintenance schedules can be adjusted to take place before the unit suffers a sudden failure. Technicians can modify the monitoring systems to determine and diagnose equipment issues; this greatly increases the efficiency of remote equipment issue diagnosis and, ultimately, real-time technical support for digital monitoring systems. The global service network comprising over 150 countries can also provide real-time technical support for digital monitoring systems.
After Sales Support Is A Reliable Guarantee
A comprehensive support system after sales services is critical in guaranteeing the stability of the unit’s operation in the long run as it relates to the maintenance of the data center generator sets. The authorized OEM generator suppliers provide a complete system for after sales services including 7×24-hour maintenance and support for the rest of your life. The global after-sales network is able to provide maintenance support cross-border so, thanks to the global after-sales network, maintenance support is provided at an extremely short time. Also, the global after-sales network provides rapid replacement the faulty component due to the global after-sales network. Every generator set, without exception, has undergone a rigid load test and, because of this, they provide the OEM with a quality guarantee for the emergency and daily maintenance of the unit. With regards to the maintenance of the data center, the after-sales team provides additional training regarding the maintenance team’s ability to perform additional maintenance.
Value of A System For Generator Maintenance
Building an all-inclusive system for generator maintenance not only offers uninterrupted power supply to the data center, but further offers commercially sustainable value to the running of the data center. Systematic maintenance planned for the generator sets facilitates the generator sets to last longer than the expected life while also minimizes the costs associated with the replacement and major repair of the units. Apart from maintenance, digital monitoring systems also provide the opportunity to avert power disruptions due to outages and the ensuing losses from the outages. For large data centers, optimizing the customers' trust and service satisfaction must be achieved by ensuring the backup power supply system works seamlessly, and causes no service breakdowns. With such accuracy, a maintenance system paired with maintenance support systems will supply an uninterrupted power supply.
