How to understand the sources of power quality distrubances
Power quality disturbances are categorized into voltage sag, voltage swell, transient, harmonic, voltage notch, and flicker. Power quality research is the study of various phenomena that cause power quality disturbance to occur and the development of mitigation strategy. Power quality distrubances can cause innumerable problems in industrial facilities. While a facility owner’s first inclination might be to blame their electric […]

What is a lead acid battery?
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Lead Acid batteries have changed little since the 1880’s although improvements in materials and manufacturing methods continue to bring improvements in energy density, life and reliability. All lead acid batteries consist of flat lead plates immersed in a pool of electrolyte. […]
What is difference between offline UPS and online UPS?
Uninterruptible power source (UPS) is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails. Online UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries, supercapacitors, […]
What is offline UPS?
Offline UPS protects against many problems in your network. Under normal conditions it conducts the input current to its outlet. When the power supply fails it switches over to a built in battery to compensate for any variations in the mains supply. Offline UPS Definition Offline UPS – also referred to as VFD (Voltage and […]
