Harmonic current
Apr , 20 2024
What does harmonic current mean Harmonic current is a collective term for the sinusoidal components whose frequency is an integer multiple of the original periodic current frequency. A harmonic current with a frequency equal to k times the frequency of the original periodic current is called a k-th harmonic current, and all harmonic currents with a frequency greater than 1 are collectively referre...

What happens when the neutral and ground wires are reversed?
Apr , 12 2024
AC power is basically generated by the generator in the power plant. The generator has three-phase windings with an electrical angle difference of 120 ° between them. When connected in a star connection method, there is a common point between the three windings, called the neutral point. This neutral point N is usually connected to the ground PE, so it is called PEN together. If the output current...

Test, use and maintenance of battery for UPS uninterruptible power supply
Mar , 30 2024
UPS battery occupies a very important position in UPS power supply equipment. At present, the maintenance-free sealed lead-acid battery widely used in small and medium-sized UPS power supplies accounts for as much as 1/4 to 1/2 of the total cost of UPS power supplies. Not only that, the actual maintenance also shows that more than 50% of UPS power failures are related to UPS batteries. Regardless ...

Choose the Smart UPS between Online UPS vs Line Interactive UPS
Mar , 14 2024
Online UPS vs Line Interactive UPS While both UPS provide full protection from major power problems, such as surges, spikes, sags, blackouts and brownouts, they differ in a few significant areas. Simply put, an on-line UPS offers a higher level of protection than a line interactive at a higher cost. More specific areas where the two types differ include sine wave output, voltage regulation, and do...
