Have you ever noticed the violet glow phenomenon accompanied with a hissing sound across the conductors of the transmission line? This violet glow across the conductor, hissing noise and the production of ozone gas in an overhead transmission line is known as Corona Effect.
Due to continuous technological advancements, there is always a need to upgrade the electrical power systems. We can make the control and supervision of power systems more proficient and competent by introducing SCADA which enables easier data collection, communication, and presentation. Read more as we cover history, features, components, applications, and advantages of SCADA in detail.
Using generators without having proper protection scheme can put equipment or working personnel in a great danger. So, there is a need to grab information about various techniques of protection required for efficient use of generators. Read more as we cover different types of abnormal conditions & faults along with appropriate protection schemes.
Work in rural, urban, or any other location, have a look around yourself and you will realize that power lines are part of the globe as they are almost everywhere. Either it is a wooden pole supplying power to the local consumers or big towers delivering high voltages, the significant hazard is present everywhere for the electricians as well as common people. All of us must be alert of the hazards we face and measures we can take to guarantee our complete safety. Linemen may be well aware of the associated hazards but other people who are exposed to power lines are usually not well taught. This piece of writing will discover such hazards and explain elementary safety actions.
Consuming electrical power inaccurately is just a waste of energy. So there is a need to learn about power-saving techniques that are being applied in industries presently. Read more as we cover power saving, its need, and the most efficient methods for this purpose.
Like any other repair or improvement project around the house, electrical work does require tools. Not only do these tools increase efficiency but they also provide safety to the user. Let's talk about how picking the right tools can help improve proficiency.This blog will discuss the most important electrical tools and equipments used in Engineering and Manufacturing Industries. Click on continue reading button to read the details of the tools you should know before buying.
Overcurrent protection is critical to personal safety and protection from a number of hazardous conditions that can result from materials igniting. Short-circuits can result in arc-flashes, which can cause severe burns and sometimes prove fatal.
A synchronous condenser is a synchronous motor running at no load and in over-excited mode. A synchronous motor in over-excited mode behaves as a capacitor which is indicated by a leading current or supply of VARs in the circuit by a synchronous motor.
Cable selection is about choosing the appropriate type of conductor and selecting a suitable size/cross-section area/ diameter of the conductor according to the application. First, there is a need to understand the significance of cable sizing and selection. Then selection criteria will be discussed keeping in mind all the derating factors that might reduce cable ampacity. A law named Kelvin's law plays a vital role in the economic sizing of conductors, so it will also be explained here. Other than the size of conductor, different types of the conductor will be studied. Also, the cable shielding and insulation will be discussed at the end.
Formerly known as Underwriters Laboratories (UL), this was a non-profit organization but now it has transformed into UL LLC, a for-profit internationally accepted safety organization located in the United States and is one of the biggest & oldest testing laboratories.
A circuit breaker is a power system protection device that can make or break a circuit.
A circuit breaker operates under fault conditions and isolates the faulty part of the circuit from the rest of it by breaking the circuit. This operation is performed automatically by employing a relay along with the circuit breaker.
Transformers are electrical devices that convert the voltage to a higher or lower value while ideally keeping the power constant.
They are an integral part of an electrical system and their application can be observed in almost all areas of electrical engineering ranging from the electrical power systems to common household appliances.
Arc Flash incident is one of the most dangerous hazards faced by electricians all over the world. According to statistics, 5 to 10 arc flash explosions occur in electric equipment every day in the United States.
In power systems, it is a common occurrence that there are unbalanced voltages and currents on the distribution side of the grid. But these voltages and currents might be unbalanced anywhere through the grid in the case of a Fault, most commonly a short circuit fault.
With the expansion of electric power in today's world, electrical power systems are exposed to many critical conditions like overvoltages and voltage surges due to lightning strikes or abrupt switching conditions. The main concern is the overvoltage condition which can cause major damage to the system's equipment. Therefore, it is necessary to install a device that guarantees protection from the condition where over or under-voltage occurs.
The short circuit is essentially an abnormal condition within a power system in which a heavy amount of current flows through the circuit.
A short circuit usually occurs as a result of a fault in a power system. The fault may be a conductor breaking and falling to the ground, or two or more electrical conductors coming in contact with each other.
As stated by the Occupational Health and Safety Administration OSHA, Lockout Tagout or LOTO is a set of specific practices and procedures to safeguard employees from the unexpected energization or the release of hazardous energy from equipment during service or maintenance activities.
The purpose of Lock out tagout is to protect the worker from any physical injury while maintaining a machine.
Load flow, also known as Power Flow Analysis, is an essential method to examine the problems occurring in the power systems network or grid.
Load flow Analysis is performed to determine the state of the equipment present in the network in order to ensure their operation within the specified limits. This study solves the steady operation state with node voltages and branch power flow in the power system.
We often hear the term 'Power Factor' in electrical power systems. But, how do we define 'Power Factor' in an electrical world?
In this article, we will be discussing power factor in detail including its significance, adversity,
calculations and a few methods for improving power.
