Lightning Strike Damage and Losses – IEC 62305
IEC 62305 identifies four main sources of damage: S1 Flashes to the structure mechanical damage, fire and/or explosion due to the hot lightning plasma arc, over-heated conductors or melted metal; …
Steel Structure used as Lightning Protection System (LPS)
The design of a Lightning Protection System (LPS) should be technically and economically optimized. Clause 4.2 Design of the LPS in IEC 62305-3 – Protection against lightning Part 3: Physical …
Effects of harmonics on Electrical Equipment
Harmonic distort the fundamental frequency of the mains voltage waveform which affects the performance of other electrical equipment and creates additional losses and heating. A total harmonic voltage distortion of …
Resistance of a Single Earth Electrode
The resistance of a single earth can be calculated if the soil resistivity is known. An earth rod driven vertically, the electrode resistance can be calculated using the following formula. …
Greenfield and Brownfield Projects
People who have been involved in project implementation may know what “Greenfield” and “Brownfield” projects mean. Prior to being employed by EPCM companies, I never knew what these terms mean. …
Designer Drafters Make the Life of An Engineer Easier
In any design project, the life on an Engineer depends on the support it gets from drafters (or draughters). The previous project I did and the current project I am …
