High Voltage Interface (HVI)

High Voltage Interface


The ACE high Voltage interface (HVI) connects between the motor power cable and the SRU. It provides an artificial Y-point from the motor power cable at the surface then translates it into a safe signal level for connection to the SRU. The HVI also provides the protective safety interface between the high-voltage three-phase ESP power and the SRU, containing a fuse and protective circuitry to limit possible damaging levels of energy from being applied to the SRU if a phase-to-ground fault occurs in the motor or motor power cable. The HVI is not required for testing the ACE system on the surface when not connected to any Voltage source. However the HVI is required to be used if connected to a motor with high voltage applied. It may be ordered as separate components to be installed in an existing high Voltage cabinet such as an output transformer. The HVI is UL/CSA Certified.
