Voltages can exist between the rig and the casing which can be hazardous during perforating operations. Stray voltages could be a sign of faults in the system. Our Rig to Casing Voltage Monitor (RIGVM) is a sensitive AC/DC voltmeter intended for continual monitoring of the potential between casings and the rig.

By using a digital multimeter, it is possible to measure whether the source of the observed voltage is AC or DC and then trace the source of any stray voltage with a view to eliminating the problem.

The RIGVM is portable, rugged and weatherproof to withstand all conditions. It measures 0 to 3V FSD DC and 0 to 3V rms AC.
