Low voltage contactors play a crucial role in many electrical systems. They allow low voltage electrical circuits to control higher voltage circuits. How Do Contactors Work? Low voltage contactors work by using an electromagnet to control the flow of electricity. They act as a switch, allowing the power to be turned on and off as […]
Low voltage disconnectors are devices that protect electrical systems from low voltage conditions. They automatically disconnect a load when the voltage falls below a certain threshold, preventing damage to equipment and ensuring safe operation. How Do Low Voltage Disconnectors Work? Low voltage disconnectors work by monitoring the voltage of a circuit. When the voltage falls […]
The vector group of a transformer refers to the phase relationship between the primary and secondary windings of the transformer. It is used to describe the way in which the transformer behaves under different operating conditions, such as when it is used to transform voltage or current. What Do Vector Groups Mean in Transformers? There […]
Medium voltage switchgears are electrical devices that are used to control, protect, and isolate electrical equipment in medium voltage (MV) power systems. MV power systems are typically defined as systems that operate at voltage levels ranging from 1 kV to 52 kV. Switchgears that are designed for use in MV power systems are typically rated […]
What are Oil-Filled Transformers? Oil-filled transformers are electrical devices that are used to either increase or decrease the voltage of an alternating current (AC) electrical supply. They consist of a core made of laminated iron or steel and two or more windings, which are coils of wire. The windings are insulated from each other and […]
Air circuit breakers are a type of electrical devices which are used to break any circuit to protect and control in case of some fault conditions like a short circuit, over-current etc. for higher currents of up to 10.000 A. In this article, you are going to find out how air circuit breakers work and […]
With developments in technology, power electronics are used more and more in the electrical sector and have become important for automation systems. It is used in all aspects within the electrical industry such as high voltage, medium voltage, low voltage, automation, or lighting systems. Medium voltage distribution substations need auxiliary voltage supply. Here is where […]
Why Do We Need Reactive Power? Nowadays, reactive power load in main grid systems is significantly increasing. Depending upon energy need, using of power transformers, transmission lines, generators, and electrical motors, lead to an increase in reactive power. That’s why controlling reactive power is important at the present time. Reactive power control relays also known […]
What Are the Cast Resin Transformers? Cast resin transformers, known as dry type power transformers have windings encased in epoxy resin. This makes the installation process easier because there isn’t cooling oil in their structure. In addition, they do not need to be contained in a fire-proof vault. The layer of epoxy helps protect it […]
Motor Circuit Breakers; what are they? Motor circuit breakers are products that protect motors against phase-loss, short circuit and overcurrent with electromechanical protection elements that can automatically switch the circuit on and off. To determine a suitable Motor Circuit Breaker, it is essential to know the power, nominal current value and operating voltage of the […]
What Are Low Voltage Surge Arresters? Protection from lightning and instantaneous surge voltages has become very important for every facility. Especially in facilities such as factories, production stops due to instantaneous overvoltage impulse that causes serious equipment damages. Surge arresters are used to protect electrical systems against overvoltage impulses. The function of surge arresters is […]
A medium voltage distribution transformer is a transformer that provides the final voltage transformation in the power distribution system, stepping down or up to the voltage used in the network lines to the level used by the end-users such as industrial and commercial properties like offices, homes, and large factories. There are two types of […]
