Common power quality issues in steel plants Steel plants deal with energy intensive processes on a daily, such as steel and aluminum smelting. Smelting is carried out with disturbing loads,...
Power quality and energy efficiency are key areas at printing facilities. Through the implementation of power quality improvement solutions, it is possible to gain substation financial and energy savings while...
The integration of battery energy storages to microgrid helps to achieve the full potential of photovoltaic (PV) systems and ensures microgrid power quality while saving diesel fuel and maintenance costs....
The electricity market operators plan their consumption and production in advance but in reality, there is a deviation within each hour. Balancing market ensures that electricity production equals to consumption...
Active harmonic filters can effectively cancel harmonic distortions from the network. This blog post will explain the key criteria that should be kept in mind when buying an active harmonic...
Voltage stability is a critical factor in electrical networks, especially when loads vary rapidly. By compensating reactive power, voltage drops and fluctuations can be significantly reduced, improving both power quality...
Electricity transmission and distribution systems are designed to carry a certain amount of current without overloading. Too much current causes excessive resistive losses in electric elements and can result in...
Inductive elements, such as transformers and magnetizing coils in AC motors, store energy into their magnetic field. The direction of the magnetic field (is such...
Power is defined as a rate of flow of energy past a given point. In electrical circuits, power is also defined as the product of instantaneous voltage and instantaneous current....
As the harmonic currents generated by the users’ equipment flow back towards the power source, they cause additional voltage distortion due to impedance associated with various power distribution equipment, such...
The load current of a purely resistive load is sinusoidal and in phase with the voltage. When the load also contains reactance, a phase-shift between the voltage and current is...
