Description
HT Instruments VEGA74 Power Quality Analyzer Repair
The HT Instruments VEGA74 is a three-phase power quality analyzer — it records voltage, current, power, harmonics, unbalance, and PQ events for power-quality surveys and energy analysis, using clamp/flex current probes. Its accuracy depends on the voltage and current measurement inputs, so that’s where service and calibration focus.
June Company repairs and calibrates the HT Instruments VEGA74 for power-quality consultants and electrical teams.
Common HT Instruments VEGA74 problems we fix
- Current-input or probe channel faults — a phase not reading from its probe input, repaired so all phases capture correctly.
- Unbalance / harmonic measurement off — the analysis circuitry, restored.
- Voltage/current readings out of spec — measurement-circuit drift, recalibrated against standards.
- Won’t log or download data — recording or interface faults, repaired.
- Display or battery faults.
FAQs
One phase isn’t capturing on my VEGA74 — fixable? Yes. Input-channel faults are repairable, then all inputs are recalibrated so your PQ data is accurate, with a NIST-traceable certificate.
Are the current inputs verified? Yes — checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
