Cyclic loading with daily, weekly, and yearly load factors
Cyclic loading with daily, weekly, and yearly load factors

Posted on 2016-08-16
Using the Neher McGrath method for the calculation of the rating of buried cables under cyclic loading conditions allows for a daily, weekly, and yearly load factor in the same calculation.

Variation of spacing between sheath bonding points
Variation of spacing between sheath bonding points

Posted on 2016-07-03
For single-core cable circuits with sheaths solidly bonded at both ends and possibly at intermediate points, the circulating currents and the resulting losses increase as the spacing increases,...

Magnetic field (EMF) : phase splitting

Posted on 2016-06-26
Phase splitting can be used to drastically reduce the magnetic fields of buried power cables. Also, the conductor cross-section can be less than half because the current is only half per split...
