Step and Touch voltage Tester

[Guilhermebr]

Hello.

Anybody help me please about step and touch voltage tester?

Metrel, red phase, mitton or another instrument are the best for step and touch voltage measurement In medium and large substation?

Hello

Metrel in usa have a good price, but it has low voltage open circuit, 50V, I can have problemas this it, when I have high impedance in remote rod, in this case red phase can is better, becouse there is 600v open circuit.

Anybody have experience touch voltage mesurement?
