The following is a description of a high voltage trip on an Enercon Compak 9000 power supply.
| Symptom, Fault |
| Symptom |
The high voltage trip light is illuminated on the display panel when the power supply is started. |
| Fault |
A breakdown in the dielectric of the electrode, roll covering or high voltage wire insulation has occurred. The fault is in the output load section of the power supply. |

| Solutions |
- Inspect the station for a failed electrode.
- It may be possible to hear a "snap" or see an arc, which will help locate the high voltage short in the station.
- To reduce the troubleshooting time, disconnect half of the electrodes to isolate the failed or pinholed electrode.
CAUTION! - When reducing the load on the power supply, limit the power demand by the same amount. (i.e. If 4 electrodes make the station load, and 2 electrodes have been disconnected for troubleshooting purposes, do not exceed 50% of the power supply's power capability.) Overpowering the electrode may cause electrode failure.
- If a failed electrode is isolated, replace the electrode.
- If the high voltage trip occurs on all electrodes, proceed.
- Inspect the station high voltage wiring, terminal blocks, and feed through tubes for defects or breakdown.
- Ensure the high voltage lead is isolated from ground and all control wires.
- Check the wiring for the electrodes including the transformer leads.
- If multiple transformers are employed, isolate each transformer.
- Check to ensure the input wires to the high voltage transformers have not shorted.
- The wires from the power supply to the high voltage transformer must be twisted at least one turn per foot and run in a non-magnetic conduit.If not, the wire insulation may melt resulting in the wires shorting.
- If problems still exist contact Enercon's Service Department.
