Understanding and Example of a One-Line Diagram for an Electrical Substation (PDF Download Available, in Spanish) This article explains what a one-line diagram is and provides an example of an electrical substation’s one-line diagram in PDF format for download and further analysis. The substation is a pole-mounted type featuring a 75 KVA transformer and a … Read more
This article presents the symbolism for electric motors. The electric motor symbol, in practice, there is a wide variety of electric motors, which means there are many symbols to represent them. You can use whichever you prefer; just remember to describe the symbol in the legend. Most symbols consist of a circle with the letter … Read more
In this article, we will calculate the appropriate fuse for a transformer. To do this, we only need to calculate the primary amperage and allow a certain margin to the fuse capacity to prevent it from blowing during startup surges. A fuse is designed to blow (open), which means it will disconnect the circuit when … Read more
The symbol of a fuse is one of the most commonly used elements in electrical and electronic diagrams. Fuses are used in electronics involving a few volts, as well as in low voltage (120/220V) circuits, and are even employed in medium voltage (over 13,000V) and high voltage (over 60,000V) systems. This article showcases some of … Read more
In this article, we explain how to use NOM-001-SEDE-2012 to calculate conduit size dimensions based on the number of wires, their gauge, and the type of insulation they use. To calculate conduit size dimensions according to NOM-001-SEDE-2012 in Mexico, you first need to understand some basic concepts related to conduit capacity for housing electrical conductors … Read more
In this article, we show a guide for selecting the appropriate electrical conductor size according to the NEC (National Electrical Code), based on the load’s amperage. Determine the Load’s Amperage Identify the current (in amperes) required by your load. This can be found in the equipment specifications from the manufacturer or calculated based on the … Read more
In this tutorial, we explain the formula for three-phase and single-phase transformers, in order to perform the calculation of power transformers. You will be able to calculate various parameters such as amperage, voltage, etc. And we suggest an app to enhance calculations more quickly.It seems that your message is incomplete or contains only HTML tags. … Read more
