Up to 32 ORPD 040 sensors capture the whole asset at onceStable gain & wide dynamic range
Maintenance free, no recalibration needed.Deep data access (TDMS)
Save raw waveforms for root‑cause analysis and model validationAccelerated FAT workflow
Cut repetitive repositioning, retesting, and idle time
Your Benefits
Laboratory‑Grade PRPD Data
ExpertHub streams high‑resolution, phase‑resolved partial‑discharge (PRPD) patterns in real time, delivering the raw evidence your specialists need for confident, standards‑compliant analysis.
Faster, Targeted Repairs
On‑board triangulation pinpoints defects before energization—no shutdowns or follow‑up site visits.
Lower Total FAT Cost
Passive fiber optics mean zero calibration or batteries. Fewer re‑tests and shorter dwell times slash labor, crane, and floor‑space charges.
Clean, Noise‑Free Signals
EMI‑immune sensors capture pristine waveforms—even inside high‑voltage factories and HV labs.
Deep Insight, Unlimited
Full TDMS files and PRPD plots are archived automatically, ready for your in‑house tools, model validation, and future audits.
24 × 7 Oversight
Leave ExpertHub connected for burn‑in or extended soak tests to catch emerging issues before shipment.
Localize partial‑discharge defects precisely in a single work‑shift. Eliminate re‑runs, minimize downtime, and keep every FAT on track.

How does it work
Passive Fiber Optic PD Sensor for Accurate Monitoring
OptiFender measures the acoustic emission signals of partial discharges and tracks their evolution over time with fiber optic PD sensors. The measuring principle behind the fiber optic PD sensor is based on acoustic emission technology.
The small and completely passive sensors can be easily installed on any kind of asset, enabling the detection of close-by internal and surface partial discharges.
The acoustic emission signals acquired by the sensor is transmitted to the acquisition unit through a standard telecommunication optical fiber. The acquired data is then displayed and analyzed through the dedicated software.
PD Localization
Partial Discharge Localization
The OptiFender system enables the precise localization of Partial Discharge (PD) sources with accuracy down to the centimeter level.
Harnessing this high-precision capability, OptiFender empowers maintenance teams to effectively identify and prioritize critical areas for intervention, ensuring optimal transformer health and longevity of the affected components.
Software

Questions and Answers
FAQ
OptiFender ExpertHub slashes costs by completing FATs in a single four-hour pass, eliminating extra labor, crane time, and bay fees; its passive fiber-optic sensors never need calibration or batteries, so you avoid recurring maintenance and consumables; one compact sensor type replaces multiple probe sets, cutting hardware and logistics expenses; and the same system can be redeployed for in-service monitoring, spreading a single capital outlay across the asset’s entire life-cycle.
ExpertHub’s rapid, one-pass PD localization flags emerging insulation faults long before they turn into outages, letting you schedule repairs instead of scrambling through unplanned downtime. By shortening FATs and delivering continuous, calibration-free monitoring in service, it shields revenue, avoids regulatory penalties and reputational hits, and keeps insurance premiums in check—all while using a single, maintenance-free sensor platform.
The OptiFender ExpetHub solution for PD sensing is applicable to all voltage levels from Medium Voltage (MV) to Extra High Voltage (EHV) without impacting the implementation cost of the system. This becomes especially advantageous for HV and EHV systems, as traditional PD monitoring solutions tend to become exponentially more costly as the voltage level increases.
OptiFender offers numerous advantages, such as cost-effectiveness across various voltage levels, adaptability to different voltage levels, accurate PD localization capabilities, retrofitting features, passive sensors that don’t need power at the sensing location, immunity to EMI and electrical background noise, long-distance operation, and precise PD sensing, allowing for immediate identification of the PD source in HV and EHV assets.
“As a service company dedicated to maintaining TSO substations, we’ve found the OptiFender product to be an exceptional tool in our arsenal.
