Ground Resistance

Note about auxiliary ground:

The auxiliary ground must be good enough for performing a proper measurement. Take into

account that a bad auxiliary ground will add a resistance in series to the circuit, lowering the

performance of the MPC unit, and therefore, reducing the capacity of injecting current to the

ground.

Corrosion on auxiliary ground terminals are a common cause of problems.

As well, a too dry terrain will affect the auxiliary ground. Pouring water over the surroundings

of the auxiliary ground or the ground pike electrode may solve the issue (safety measures

should be taken to avoid shortcircuit when using/carrying water on electrical instalations)
