AC DC rectifier: alarms and lockouts due to current and voltage

alarm AC DC rectifier

It’s important to understand what we mean when we talk about alarms and lockouts in the AC DC rectifier for telecommunications due to malfunction. This implies that the equipment goes outside its established range of parameters. If the failure doesn’t compromise the integrity of the AC DC rectifier or the service it provides, only a […]

Calculation of DC voltage drop by commercial conductivity factor

Calculation of DC voltage drop

One of the factors that must be given special attention when selecting electrical conductors is the power losses that occur in them. For this reason, we present the Calculation of DC voltage drop by commercial conductivity factor. There are 2 methods to determine the voltage drop, the one we will study here uses the resistivity […]

Parallel connection: what it involves

parallel connection

In this post called Parallel connection: what it involves, we will discuss one of the two configurations of electrical circuits. In terms of their connection, which is valid for both energy sources and loads. However, in this article, we will focus on connections at the level of DC sources, their characteristics, and uses. Let’s take […]

How to perform the discharge test of a stationary battery bank

different types of batteries for discharge test

Knowing the operational status of a stationary battery will save you from many unpleasant surprises. That’s why the battery discharge test is one of the most reliable methods. It will indicate whether they are capable of fulfilling their mission and if they retain the design attributes expected of them. An example of the latter is […]

Components of the power distribution panel. Part 2

Power distribution panel

This post is the continuation of the article related to Components of the power distribution panel. Part 1. Here, we will analyze the operation of the Rectifier Module and the Control Module. The first one acts as a source that energizes the second one and this, in turn, supplies DC power to the telecommunication loads. […]
