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.

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.

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 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.
