Different types of UPS

Aug , 26 2021

An Uninterruptible Power Supply refers to a power system that provides emergency power to a load when the input power source or mains power fails, regarded as near-instantaneous protection from input power interruptions. The three general categories of modern UPS systems are online, line-interactive, and offline. Offline UPS: In an off-line ("standby") UPS system, the load is powered directly by t...

Online High Frequency UPS and its advantages

Aug , 26 2021

High frequency UPS: High frequency UPS is usually composed of IGBT high frequency rectifier, battery converter, inverter and bypass. The IGBT can control its opening and closing by adding control to the gate. The switching frequency of the IGBT rectifier is usually from thousands of Hz to tens of kHz (even up to a hundred kHz) relative to the 50Hz frequency that is far higher than the low f...

Backup batteries for Oil & Gas industry

Aug , 27 2021

Oil provides one-third of the world’s energy supply. Natural gas brings it up to over 50 percent. Modern economy would collapse without ongoing production to keep up with the demand. Petroleum products and natural gas account for 99.99% of powered transportation around the globe. The oil and gas industry works in some of the most challenging places on the Earth, in extreme weather, harsh con...

How to charge Lead Acid Battery properly?

Aug , 31 2021

A battery is an electrochemical device. During the battery discharge process, the stored chemical energy is converted to electrical energy that is used to power an electrical load. The charging process is the opposite reaction, where the electrical energy from the charging source is being stored into the chemical energy of the battery. In this article, we will know about the procedures of charging...

The basics of Solar Panel

Aug , 31 2021

What are solar panels made of and how do they work? Solar cells are made primarily from silicon, a chemical element with conductive properties. Exposure to light changes silicon’s electrical characteristics, which generates an electric current. A cell is a small square of silicon (about 6” x 6” or 5" x 5") with electrical contact plates on the face. Solar panels are made by laying out a grid of th...

What is Solar Water Pumps?

Aug , 31 2021

Solar water pumps are a relatively new concept in mechanics. Through solar panels, the pump can eliminate the cost of energy and provide a more feasible option that uses energy from the sun (and not fuel-burning mechanisms) for pumping water. Therefore, a large quantity of energy is being released right at the time when it is needed the most. Components: The main components in a solar pumping syst...

Integration of ESS with Renewable DC Micro grids

Sep , 01 2021

Renewable energy based micro grids are emerging as a viable solution for isolated rural areas or oceanic islands. The main issue which plagues its development is the variable/intermittent nature of renewable sources, which makes it tough to achieve smooth operation. Such fluctuation may lead to load imbalance, instability, and damage to system components under the influence of varying loads. In su...
