Variable Frequency Drives form an essential part of any manufacturing plant. Its continuous operation is necessary for maintaining a plant’s output, and any failure results in a chain reaction, effectively bringing the entire industry to a standstill.
Electromagnetic Interference is a common phenomenon in a world which is embedded with electrical circuits. In a nutshell, EMI or Radio-frequency Interference is a disturbance that is generated by an external source like power lines, variable frequency drives, magnetic contactors, etc. effecting electrical circuits in its proximity.
With the increasing requirements for space saving control panels, the risk of Electromagnetic Interference is bound to increase, adding complexity to their designs & shielding techniques.
Every year, the world discharges 2 million tons of sewage, industrial and agricultural waste, polluting waterways and directly killing 1.8 million children from waterborne diseases. This statement alone should be enough to encourage an effective framework for increasing a country’s capacity to treat wastewater for a healthier environment.
With new technology advancing the flow of data and connecting every machine with algorithms and sensors, there are so many new possibilities for improving production. But what comes along with all these monitors, tracking systems, sensors, and devices? Large amounts of data.
Automation not only cuts costs and saves time but instills reliability and precision within the system that has immediate and long-term benefits. Today home automation or hobby projects often conjure images of teenagers working on Arduino, Raspberry Pi and PIC, but the true struggle to make industries and large-scale systems independent began more than five decades ago.
Electrical control panel design basics is a vast field, dotted with problems pertaining to management, visual appeal, reliability and safety. The design basics for control enclosures that house various components from Programmable Logic Controllers (PLCs) to high-voltage relays is dependent on several parameters, however, keeping down the cost is one that can’t be sidelined at any time.
Testing the transformers in your factory is essential to keeping your production running safe and efficiently. The following are 12 standard tests to check your transformers:

Soft Start and VSD: Basic Principles
Electric motors do not just switch on and off from a dead stop to operating speed. Rather, these motors get turned on by accelerating relatively slowly until they reach their desired speed. This speed “ramping” is necessary to keep the motors from burning out due to overloading, and the most common way to achieve this ramping effect is to drive the motors with either a soft starter or variable speed drive (VSD).

Fuses are an overly abundant electrical component, and they come in all sorts of shapes and sizes. This would make picking out a replacement easy, except there are so many types of fuses out there that the likelihood of two aesthetically identical fuses having the same operating specs is pretty low. This identity crisis can lead to mistakes in selecting a new or replacement fuse, which puts workers and equipment at risk.
Ladder Logic 301: One Shots
Through this series on ladder logic, you have been given an introduction to the basics of ladder logic 101 and you have seen some of the upper level conceptual ideas behind the use of ladder logic in PLC systems. To end the series for now, it is necessary to add one more concept to the list, and that is the use of one shots to control signal durations.
