Lightning Protection


Lightning Protection for Transmission Lines
Probablistic analysis combined with required maximum outage rates, shielding angles and tower footing resistances and EMTP software is used to determine shielding requirements for HV transmission lines.

Lightning Protection for Structures & Electronic Systems
The risk of damage to electronic system or structures is dependent on the lightning activity in the area. The risk increases with the size of the plant and the consequences of a lightning strike to a large industrial plant could have large financial implications. While the risk of physical damage to primary plant is low in most cases, secondary damage to control and instrumentation equipment and power supplies is very likely.

Lightning affects electronic systems in a number of ways. Electronic systems sometime suffer from the effects of direct strikes but most often, the systems are affected by induced surges from nearby strikes. Sometimes, a strike that occurs even relatively far away can have a disastrous effect on the electronic system.

Lightning and Surge Studies
Using CDEGS™ the transient response of a conductive structure can also be modelled, using frequency domain analysis. The lightning impulse response of earthing/grounding systems can also be analysed.

We offer the following lightning protection services:
