Omicron VOTANO 100 Transformer Tester Repair
The Omicron VOTANO 100 is an instrument-transformer (CT/VT) analyzer — it measures the ratio, phase, excitation, and accuracy class of current and voltage transformers to verify metering and protection instrument transformers, PC-controlled. As a precision measurement-and-source instrument, its faults concentrate in the output/excitation amplifier, the precision measurement front-end, and the timing/control and communications — not the relay-test faults its category label implies.
June Company repairs and calibrates the Omicron VOTANO 100 for instrument-transformer and substation test teams.
Common Omicron VOTANO 100 problems we fix
- Output-amplifier rebuilds — the excitation/output amplifier weak or dead, repaired so it drives the transformer under test correctly.
- Ratio / phase measurement off — the precision measurement front-end drifting, recalibrated against standards.
- Timing / control faults — measurement sequencing wrong, corrected.
- Won’t connect to the control PC — interface/communication faults, repaired.
- Power or input faults.
FAQs
My VOTANO 100 ratio results look wrong — fixable? Yes. Output-amplifier and measurement faults are repairable, then recalibrated so CT/VT ratio, phase, and accuracy results are trustworthy, with a NIST-traceable certificate.
Is the measurement verified? Yes — checked against our standards along with the output.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
