How not to select the wrong generator set (genset) for your application
Generator set is maybe the most expensive part you can find in a substation. Therefore, many factors must be considered when determining the proper size or electrical rating of an electrical power generator set. If wrong size or rate is…...

The magic I used to reduce harmonics in a plant (a real case study)
During the last several decades, the number and severity of electrical engineering problems caused by harmonic distortion have been significantly increased in both, domestic and industrial environments. This is mainly due to the increased number and larger ratings of nonlinear…...

Practical tips for installing surge protection devices in low voltage panel
In an electrical systems, surge protection devices (SPDs) are usually installed in tap-off configuration (in parallel) between the live conductors and the earth. The operating principle of SPD can be similar to that of a circuit breaker. In normal use… Read more

How harmonic filters prevent distortions in networks with high harmonic levels
The subject of this technical article are harmonic filters and their design. Filtering measures are recommended and may be required for electrical systems with too high harmonic levels. Filter circuits can absorb more harmonic currents. This means that, like reactor-protected… Read more

Theorems and network reductions that every electrical engineer MUST know
Most practical power system problems are solved by using steady state analytical methods. These methods make the assumption that circuit parameters are linear, bilateral, and constant for constant frequency circuit variables. When analysing initial values, it is necessary to study… Read more

Properly engineered and installed selective coordination between LV circuit breakers
It’s extremely important to work on selective coordination of circuit breakers in the design phase of a system. After switchboards, distribution panels, MCCs, lighting switchboards, etc. are installed, there typically is little that can be done to retroactively “fix” a… Read more
