Addressable Voltage Switch
The Addressable Voltage Switch is designed to provide both over-voltage and over-current protection for Owens GoFire addressable switches to remove any possibility of unplanned detonation if excessive power is applied either accidentally, or from another source, at surface.
The tool comprises of 2 identical boards which are both checked every time the tools are powered up or at the end of a run. If either of the boards fails while in hole the system will automatically alert the engineer and switch to the back up board. This ensures that even if a board does fail – the job can still progress seamlessly. The AVS allows Owens GOFire system to be fully compliant with the latest 3rd edition of API RP67.
Isolates excess voltage and current from perforating string
Has back up boards to ensure if/when a component fails the back up board will ensure the job is a success
