The intricacy of medium-voltage circuit breaker ratings

2 weeks ago | electrical-engineering-portal.com | Edvard Csanyi

Medium Voltage Circuit BreakersWhen you look at the IEC 62271-100 for MV breaker ratings, you will likely find a bunch of rated-something ratings. It could be hard for young engineers to catch up with all ratings, especially since several ratings are similar in wording but crucially different. This technical article will shed some light on the most important of these ratings of a medium-voltage circuit breaker.

The Art of Shunt Reactor MonitoringNowadays, monitoring of transformers and shunt reactors is pretty much common. However, the difference is in the nuances. There are dozens of parameters that can be monitored and the the overall cost is not negligible at all. There are many benefits of monitoring the reactor operation, and the moist important is to prevent damage that could end shunt reactor life.
Seven steps to improve visual impact of a power substation

1 month ago | electrical-engineering-portal.com | Edvard Csanyi

Substation’s visual impactThe aesthetics of the substation should be of greatest significance to the community. To ensure environmental compatibility and community acceptance, it is vital to involve the community in the early stages of a project. It is possible that environmental impact assessments were not conducted during the initial installation of several of the current substations, which date back tens of years.
What is Time Grading in Relay Protection

Grading operating times of the relaysWhat are time grading and relay coordination in protection philosophy? Let’s try to figure out how to grade (or rank) the relays’ operation times so that the one nearest the problem operates first. In Radial Distribution Systems, time-graded protection works well. Systems that begin with an electrical source at the top and end with a load at the bottom are known as radial distribution.
Turnkey Substation Project

Turnkey Substation ProjectBehind the successful execution of a turnkey substation project is always successful project management. Young engineers working on the execution of substation projects often repeat the same mistakes that often lead to unforeseen project costs. Generally speaking, management of turnkey projects can be described as monitoring and checking of various items and activities in a turnkey project based on the contract document and specification.
Technical Documentation for a Turnkey Substation

What is a Turnkey Substation? A Turnkey Substation is a substation that is designed, constructed, and commissioned by a Service Provider according to the specifications established by the Customer. A Service Provider is an entity (business) that provides services to other entities (companies).
How to configure medium voltage switchgear

Medium Voltage SwitchgearLet’s discuss the most critical factors that influence the correct configuration of medium-voltage switchgear. As you will see below, for the most common applications of MV switchgear, there are at least six main categories that are very important in the design of future power distribution.
Good operating practices for switchgear circuit breakers and contactors

Jan 20, 2025 | electrical-engineering-portal.com | Edvard Csanyi

Operation of LV/MV SwitchgearThe purpose of this guideline is to provide suggested practices for the operation and inspection of medium voltage (2 to 13.8 kV) and low voltage (200 to 480 volt) draw-out switchgear circuit breakers and contactors. Good operating practices are critical to obtain the best service and performance from plant equipment and to ensure a safe environment for plant personnel.

It is often confused with motor rotation.
Best practice for providing LV supply into high earth potential rise sites in substations

Dec 22, 2024 | electrical-engineering-portal.com | Edvard Csanyi

The danger of earth potential riseDuring the passage of earth-fault current a substation earth electrode is subjected to an earth potential rise. Potential gradients develop in the surrounding ground area and these are highest adjacent to the substation earth electrode. The earth potential rise reduces to approximately zero (or true earth potential) at some distance from the substation earth electrode.
