Foire aux questions

Do we really need fluorescent fiber‑optic temperature sensors on every transformer?

Not on every unit. Prioritize critical transformers where failure impact is high or loading is aggressive. For standard units, use modelled hot‑spot with the integrated oil temperature/level/pressure device as baseline. This keeps total cost balanced while securing the biggest risk reductions where they matter most.

What is the practical advantage of fiber‑optic hot‑spot over RTD/thermistor?

• Accuracy at the hot‑spot: Direct measurement vs. model estimates.
• Immunité aux EMI: Reliable data in high electrical noise environments.
• Faster response: Captures thermal transients for better derating decisions.

What does the integrated oil temperature/level/pressure device replace?

It replaces separate analog gauges and scattered sensors with one digital unit. You receive correlated alerts, simpler wiring, and clean data into SCADA. It is the recommended baseline for most assets and pairs well with fiber‑optic temperature on critical units.

Will installation require an outage?

Article	Typical Requirement	Remarques

How often should we run lab oil analysis if we have online sensors?

Keep periodic lab panels for cross‑checks and broader chemistry. Typique: quarterly for Tier 1, semi‑annual for Tier 2, annual for Tier 3. Online gas/moisture complements but does not fully replace lab depth.

What’s the recommended mix of CapEx et OpEx for a first year program?

CapEx on fiber‑optic (for critical units) et le integrated device (fleet baseline). OpEx for lab panels, étalonnage, and quarterly reviews. This mix delivers early risk reduction plus consistent data for decisions.
