Love the idea behind this device. Shunt arc flash energy from the worker and make the fault quicker. This was introduced a few months back and it has been a real innovation that can be retrofitted for older style equipment.

Sad another fatality which used to be common in the US. Grounding has almost totally eliminated these. The US OSHA 1910.269 legally required grounding in most medium voltage to high voltage applications or the worker must consider the conductors energized. Additionally arc rated clothing has been shown to save some shock victims. [...]

It is commonly believed around the world that arc flashes are “freak accidents” just as most believed in the US in the early 1990’s but groundbreaking work by individuals like Ralph Lee, companies like Duke Energy, Dupont, Bussman, AB Chance LG&E Energy (eON) and our ASTM committee have shone the light that electric arc flashes [...]

“Kyushu Electric Power Co. said three workers were hospitalized with minor burns and four others were also hurt after sparks flew from electric devices while a regular inspection was being carried out on the No. 1 reactor of the Sendai nuclear plant in southern Japan.”

“An electrical contractor has been convicted and fined on Wednseday over an electrical accident involving a trainee.

In 2007, ICE Engineering and Construction Pty Ltd had engaged the then 17-year-old man as a trainee. Sometime around April of that year, the trainee was assigned to a local business to help with work on a circuit distribution board.

He was using an insulated copper to touch a circuit breaker’s live part when an arc flash resulted.

The young man was knocked to the ground and suffered burns to his neck, face, and arms.”

No.
This blogger is very knowledgeable but wrong in assuming the IEC standards cited prevent all arc flashes. Incident data in all countries indicate the contrary. While there are NO standards for work practices in most countries depending on IEC design standards may help prevent many injuries but they will not prevent all [...]
