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

The theory behind reactive energy compensation that every engineer should know
Reactive energy compensation is an essential process in improving energy efficiency. It reduces the power consumption and thus its cost, enables optimum use of installations by preventing them being oversized, and more generally it improves the quality of energy systems…. 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
