Live line wash
Worked on a power station south west of Alexandria where the switchyard was 500KV!Live line washing was installed by contractors and consisted of several sets of fine water jets aimed at the insulators(they could get coated with sand/salt particles being near the desert).First test,loud bang followed by turbine trip!!Happened twice and it was found that the jets were at the wrong angle!
Working in Riyadh I was chosen(guini pig) to demonstrate a hot stick on a 275kv transformer,try not to look scared said the vendor of said hot stick!!!So with thick rubber gloves I prodded the live terminal and got the red light!!Was I scared?....Yes!!
