Voltage Gradient Probe

The Voltage Gradient Probe (VGP) is a robust, hand-held, subsea unit used to give an easy interpret indication of AC electric field strength in sea water. The VGP's primary use is to indicate to divers or ROVs the presence of any local AC electric fields while working on subsea electrical equipment. The VGP gives an indication of the presence and magnitude of the AC electric field in an easy to interpret 'traffic light' configuration.
- The VGP comes with a dedicated Testbox which allows functionality to be tested prior to deployment by following a quick, simple and intuitive procedure.
- Indication of presence and magnitude of the AC electric field using a series of 6x LEDs which illuminate progressively at clearly defined trigger voltages.
- A dedicated Battery Status LED provides a clear indication of the battery status and provides confirmation that the unit is functioning.
- Developed with reference to IMCA standard D 045, R 015.
