Corona, Thermal & Acoustic Imaging Equipment
UV corona cameras, thermal imagers, and acoustic imaging tools for high voltage inspection, partial discharge detection, and electrical predictive maintenance.
Most electrical failures give warning signs before they become outages. Corona discharge degrades insulators and hardware silently. Hot spots build in connections and components over time. Partial discharge quietly weakens insulation. The right imaging tools make these invisible problems visible — without taking equipment out of service. ProgUSA supplies UViRCO corona cameras and FOTRIC thermal and acoustic imaging instruments to utilities, electrical service providers, and industrial facilities across the United States, backed by application support, training, and service from our Florida tech center.

UAV Cameras
UViRCO CoroCAM 8HD UAV
Aerial Inspection System A UAV-mounted version of the CoroCAM 8HD, sized and balanced for standard commercial gimbal designs and enterprise-grade UAVs. Enables aerial inspection of transmission lines, substations, and hard-to-reach overhead hardware from multiple angles without requiring outages. Key capabilities:
- Combined thermal IR, solar blind UV, and visible camera on one UAV payload
- Fits standard commercial gimbal designs
- Remote control via standard radio controller
- Allows inspection from multiple directions on overhead hardware
- Enables EPRI-based maintenance priority assessment from the air
- Quick installation on UAV or tripod
POWER UTILITIES can use CoroCAMs for a variety of tasks related to the physical hardware, from installation qualification to contamination assessment to maintenance priority assignment along the entire electrical supply chain, from generation to consumption.
GENERATION: Degraded insulation on windings of generators or motors results in reduced efficiency. Partial discharges occurring at these points also cause further damage. During maintenance shutdown, CoroCAMs can be used to inspect the disassembled & energized rotor or stator for discharges.
TRANSMISSION: Various Transmission Line hardware can become sources of electrical discharges and may be susceptible to damage by the corona phenomenon. The necessity for line washing may be indicated by surface arcing.
DISTRIBUTION: Distribution Line hardware are less likely to have detectable corona, but arcing and sparking line faults are just as probable. The necessity for line washing may be indicated by surface arcing.
SUBSTATION: Various Substation hardware is susceptible to electrical discharges. The necessity for substation washing may be indicated by surface arcing.
CONSUMPTION: The consumption of electricity in various faulty devices can lead to electrical discharges. In many cases, the air ionization may be detrimental to humans nearby.
ProgUSA has integrated the new UViRCO Model UVS1 compact HD corona camera on the DJI M300 drone and the WISPR Ranger Pro 1100 drone, which is US-made and NDAA compliant.
