Status: Current Production. We repair and calibrate all of them.
Common HVI CDS / VT Series Problems We Fix
- Weak or no thump / surge energy down — surge capacitor bank degradation
- Won’t fire or surge intermittent — HV switching thyristor or IGBT failure
- TDR trace weak or won’t pre-locate faults — receiver sensitivity loss
- HV cable or connector arcing / insulation breakdown
- DC hipot readings drifting or inaccurate
- Control processor or display not responding
- Safety interlock won’t clear / won’t allow a shot

Frequently Asked Questions
How much does HVI CDS / VT Series repair cost?
Repairs start with a flat evaluation fee that’s credited toward your repair cost. After we diagnose the instrument, you get a firm quote before any work begins — no surprises.
How long does the repair take?
Most HVI CDS / VT repairs are finished within 5–10 business days of arrival, with expedited turnaround available if you need it back fast.
My thumper has weak or no surge output — can you fix it?
Yes. Surge capacitor bank degradation from repeated high-energy discharges is one of the most common faults on these systems, and it’s fully restorable to rated surge energy.
The unit won’t fire or surges intermittently — is that repairable?
Yes. HV switching thyristor and IGBT failures that stop the system from firing or cause intermittent shots are a routine repair, restored for reliable thumping.
My TDR won’t pre-locate faults like it used to — can you repair that?
Yes. TDR receiver sensitivity degradation that weakens the trace and makes pre-location difficult is repairable, restored so you can pinpoint faults before thumping.
My readings are drifting or out of spec — can you recalibrate it?
Yes. We verify output voltage, DC hipot metering, and the safety functions against our reference standards and return the system with NIST-traceable results on a certificate.
Can you repair arcing HV cables or connectors?
Yes. High-voltage cable and connector insulation breakdown that causes arcing is repairable, restored for safe, reliable high-voltage operation.
What if my exact model isn’t listed?
We service every HVI CDS / VT Series configuration. If your model isn’t in the table, pick the closest match or email us — the process is the same.
Who uses the HVI CDS / VT Series?
Electric utilities, underground cable maintenance crews, cable testing contractors, and municipal power distribution teams rely on the CDS and VT systems to locate faults in underground power distribution cables.
