Spiking of cables

[TVH]

When should cables be "spiked" and how should it be done?

I thought you "spiked" a cable to verify it is de-energized before working on it.

You spike a cable "hoping" it is de-energized

You sure you are not thinking of staking cables. Had an engineer that wanted 15KV direct buried cable staked and tied before being back filled with sand. He wanted them kept in a tight triangle shaped group with no cross overs.

The video Ron referred to is good to see what a spike test is on a cable. When done in the field it is done to verify that a cable has be de-energized prior to cutting the cable. In the utility we speared (spiked) a cable using an hydraulic spear with the manual pump located away from the manhole (just in case we got the wrong one). The spear penetrates the jacket and shorts the conductors.

Scott,
The one I linked to in post 3 is a remote hydraulically operated spike.
