Capacitive Coupling Between Adjacent Conductors
A static electric field has no ability to deliver any power or energy to something that might be used to measure its presence. Just like a capacitor carries no DC current when a constant DC voltage is applied.

However, static electric fields can be measured by using an electric field mill: -

This performs commutation of the field to produce enough current to drive a meter but, energy is removed from the field and as such the field is somewhat disrupted and there is of course a fundamental error involved with this type of measurement.

In terms of the "mill" an alternating electric field autocommutates and therefore power can be extracted to drive a meter and make a measurement.

Basically, this means that static crosstalk to other "wires" is of no consequence because no current can be involved and natural impedances present on wires to ground force the crosstalk effects to be zero. Not so with alternating fields because a capacitor conducts current proportional to the rate of change of voltage between its terminals: -

Q = CV and dQ/dt = C dV/dt = current.
