Degradation or corrosion can be caused by: Overcharging batteries. This can cause degradation and eventual failure of the battery. Consistent overcharging can cause thermal runaway, where continuous rising temperature and rising current result in battery case rupture or possible fire. Discharge cycle issues.
it facilitates charging the battery independent of the DC system. Following a repair, or especially following a capacity discharge test, charge voltage can be elevated (beyond the rating of isolated downstream equipment) to increase the recharge rate and reduce time, or voltag
DC power maintenance refers to maintaining or replacing battery cells and systems to restore their performance and reliability at a fixed time, interval, or usage, regardless of their condition. (Credit: ERS) Two commonly practiced strategies for DC Power Maintenance are time-based maintenance.
If the uninterruptible power supply (UPS) batteries supporting critical networks or the battery banks supporting electrical protection and control, emergency, or backup systems fail, the consequences can be significant. Personnel safety, equipment, and facility operations are at risk during those 10 seconds.
Today’s maintenance practices offer a spectrum of UPS and battery system periodic maintenance services specifically designed to ensure the reliability of the electrical power chain and meet all compliance requirements throughout the equipment’s lifecycle.
DC power systems are critical to ensuring the continuity of an organization’s operation and are often neglected. Damage to reputation and costs to the business can quickly escalate due to power fluctuations. UPS systems provide a constant, steady flow of clean power to critical equipment and facilities that cannot tolerate even the slightest power fluctuations.
