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 likely.
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 ionisation may be detrimental to humans nearby.

INDUSTRIAL CUSTOMERS use CoroCAMs to preform Quality Assurance test on produced products or inspect their own transformer yards and HV infrastructure to identify parts to be maintained before they fail. Producers of Rotating Machines and High Voltage hardware not just inspect their hardware in the Q/A activity, but also after installation at their customers.

RESEARCH & DEVELOPMENT activities at HV Consultation labs or at Universities can use CoroCAMs to perform failure analysis or to test if the prototypes of new hardware designs / configurations will indeed be discharge free as modelling software indicates or do new fundamental research by visualising discharges.

TRANSPORTATION CUSTOMERS like Railways use CoroCAMs to inspect their power supply network and the catenary. Airports inspect their HV and radar systems and use the CoroCAMs to help identify sources of radio interference.
