Welcome to another video here on our channel! In this video, we brought an assembly that is much requested by you here on the channel: WHAT IS AN AUTOMATIC CAPACITOR BANK? This is the first video in a series in which we will show you the assembly of a six-stage automatic capacitor bank from scratch. And we ask that you don't miss any episode! This capacitor bank has a power of 45KVAR, divided into 6 stages of 7.5KVAR. Therefore, we chose the 6 capacitive cells with this capacity, as well as specific contactors for this type of application, which have what we call a damping resistor or pre-charge resistor. In short, whenever you are assembling a capacitor bank, it is recommended to use this specific type of contactor! For the power circuit, we will use a molded case circuit breaker and 6 circuit breakers of the same type (one for each cell). To control the power factor in the network, we will use a 6-stage automatic controller, which you will be able to see how it is installed. Finally, we will also use components that are more familiar to you, such as turn signals and selector switches. If you want to learn from those who teach what they live, stay tuned so you don't miss any details, because today's video is under the dual command of the Ambassador and the Captain, and it is unmissable! #embaixadordecomandosengehall #NoComandoDelas ---------------------------------------------------------------------------- Power Factor Correction – What is it and why is it important? You may not know, but some problems in your installation may occur due to not having performed a power factor correction. Overloads, voltage drops and losses are some examples. Calculating the power factor and correcting it are two fundamental steps in energy management and efficiency. Maintaining the power factor, as close as possible to 1, is regulated by Brazilian legislation through decrees. These decrees determine the manner of evaluation and the method of billing for energy that exceeds the new limits. But what is power factor correction? First, we need to understand what a power factor is. Also known as PF, the power factor is a number between 0 and 1 and measures the efficiency of electrical energy consumption of a circuit or equipment. The standard power factor is 1, that is, the lower this number is, the lower the efficiency of the circuit or equipment, and the closer it is to 1, the higher the efficiency of the circuit and, consequently, the better the performance. Power factor correction seeks to make the electrical grid much more efficient through the installation of capacitor banks. The purpose of the banks is to “nullify” the voltage and load current curves. Why is the power factor low? There are many possible causes for a low power factor (remembering that the ideal is to be as close to 1 as possible), such as: motors operating without load, induction furnaces, oversized motors, reactors with low power factors, transformers operating with loads below the established maximum, and others. The most important thing is that the professionals responsible pay attention to this measurement to avoid future problems. But why is it so important to correct the power factor of an installation? In addition to maintenance being required by law, power factor correction is important to avoid some problems such as: voltage drops, underutilization of capacity, losses in the installation, overloads, and extra charges. Knowing that a CAPACITIVE load advances the current and an INDUCTIVE load advances the voltage, we try to combine the two to obtain the best possible power factor, or as close to 1 as possible, by interconnecting capacitors (or banks of several capacitors for larger loads) simultaneously with our inductive loads. The necessary capacitance is a consequence of how much this current is out of phase, and needs to be calculated by a specialist. So if you have an industry or company that uses a lot of heavy motors, even elevators, you need to pay attention to the correction of the power factor. On your monthly electricity bill, you may be charged excess amounts due to reactive power. If this is happening, we recommend installing a capacitor bank in order to correct this power factor and consequently avoid extra charges. Source: https://www.ampher.com.br/
