A variable resistor, also known as a potentiometer, is a fundamental electronic component that allows manual control over the amount of resistance in an electric circuit. Its primary function is to regulate the flow of electric current by adjusting the resistance, enabling precise control over voltage, current, or signal levels.
IEC 60079 is a sequence of global standards developed with the aid of the International Electrotechnical Commission (IEC) that addresses the device utilized in explosive atmospheres, wherein there may be a chance of hearth or explosion due to the presence of flammable gases, vapors, or flamable dusts.
In general, the sizing of earthing conductors is based on the following principles, we will discuss earthing cable size as per IEC 60364-5-54
IEC 61000-5-2 is an international standard that provides guidelines for characterizing the immunity of industrial environments against voltage dips, short interruptions, and voltage variations on the electrical supply. This standard is a part of the IEC 61000 series, which addresses electromagnetic compatibility (EMC) issues.
A flyback converter, also known as a flyback transformer or buck-boost converter, is a type of switched-mode power supply (SMPS) used to convert one DC voltage to another. It is commonly used in low to medium-power applications and has unique features that make it suitable for a variety of electronic devices and power sources.
IEC standard for instrument earthing, also referred to as grounding, play a crucial role in ensuring the safety, reliability, and performance of electrical and electronic systems. To achieve these objectives, compliance with the International Electrotechnical Commission or IEC standard for instrument earthing is of utmost importance.
Carbon credits have emerged as a critical weapon in the global fight against climate change. These credits provide a realistic way to cut greenhouse gas emissions while also promoting sustainability. In this post, we will look at the notion of carbon credits, the Clean Development Mechanism (CDM), and the certification process for selling carbon credit.
Another name for the utility factor in a power plant is the utilization factor. It is a crucial performance indicator showing how well the facility uses its electricity production.
Plant Factor is a key performance metric for power plants, which compares the actual amount of electricity generated to the maximum amount that might be produced under perfect circumstances. It offers perceptions of the dependability and operational efficiency of power-producing plants.
An IGBT rectifier, also known as an “Insulated Gate Bipolar Transistor rectifier,” is a kind of rectification circuit that uses IGBTs to change direct current (DC) from alternating current (AC). IGBT rectifiers are widely used in many different applications, especially in power systems and industries where accurate control of DC voltage and current is crucial.
We will explore the differences between thermistor vs RTD vs thermocouple, focusing not only on commonly discussed features but also on technical distinctions
Thermistors and RTDs are two types of temperature sensors. We will explore the differences in thermistor vs RTD accuracy, highlighting both well-known and technical distinctions.
RTDs and Thermocouples have the same function of temperature measurement but there is a significant difference between RTD and thermocouple when we study the design
At the heart of the DC current transformer working principle is its core and coil arrangement. Similar to AC transformers, DC current transformers consist of a magnetic core and primary and secondary windings. The primary winding, typically consisting of a single turn or a few turns of a thick conductor, is connected in series with the DC circuit carrying the current to be measured.

Demand factor for motor loads refers to the ratio between the actual power consumed by a group of motors and the maximum potential power that could be consumed if all the motors were running simultaneously at full load. It is an essential parameter used in electrical engineering and design to determine the total electrical demand of a system accurately.
The NEC demand factor is a crucial component of electrical design, as prescribed by the National Electrical Code (NEC). By incorporating demand factors, electrical designers can accurately determine the expected maximum demand on an electrical system, ensuring safety and efficiency in electrical installations. In this article, we will delve into the concept of the NEC demand factor, its significance, and its application according to the NEC guidelines.
