Lightning and Voltage Rise … are you ok?

HOW DO YOU COPE ON YOUR SITE?

This is the archetypical, (meaning “Image from the unconscious” I thought I’d throw that in to make it seem more technical), lightning bolt, one that arcs out of the sky and smites the ground with a great, often flickering flash of light.

Lightning is the sudden release of built-up charge stored in an electric field, though exactly what triggers it remains a mystery.
Do you see sights like this on your site?

Have you controlled the risks?

Mining and Quarrying Safety and Health Regulation 2001 –
31 Voltage rise

The operator or site senior executive must ensure voltage rise in an electrical installation at the mine caused by lightning strike, static electricity, voltage surges and other transient voltages is limited to a level necessary to achieve an acceptable level of risk, having regard to the ways stated in a guideline for limiting voltage rise.

Depending on where your site is, and how many lightning days per year you have, will vary your approach to how you handle lightning and the accopaning voltage rises.
