reliable corona cameras for daytime inspection

Ofil offers a wide selection of genuine cameras and imaging systems for the detection of corona and arcing. Ofil's systems are being used by engineers to prevent and manage electrical equipment failure. Ofil is commited to manufacture reliable testing equipment and provide expert advice to ensure that each customer gets the proper solution.

Ofil's DayCor® cameras are used by reliability engineers to prevent and manage equipment failure. Ofil's systems include: bi-spectral UV-Visible cameras and UV imagers classified as NonDestructive Testing (NDT) equipment. IR and UV inspection are complementary technologies. As such, a comprehensive maintenance approach requires inspection by both thermal imaging cameras and UV cameras.

Ofil is the market leader manufacturer whose systems are renown for having the highest sensitivity to UV discharge. Ofil's systems are being used globally. DayCor® corona cameras are used by electrical utilities for inspection of high & medium OH transmission lines, Distribution, Substations, Motors' workshops, High-Voltage Laboratories, Mines, Refineries, Heavy industry, Data centers and other, as handheld, airborne, vehicle mounted and standalone railroads.

Predictive & preventive proactive activities intend to prevent equipment failure. Facilities dedicate resources to these proactive maintenance and minimize thereby high repair cost and unexpected shutdown. Reliability management involves using reliable instruments that indicate and pinpoint faults and potential faults on time, precisely, and easily.

Why use corona cameras?

Corona discharge is associated with high voltage apparatuses such as electrical transmission lines, transformer insulators and bushings, high-voltage suppliers, switchgears, motors and the like.

Corona is often a sign of a defect, contamination, malfunction, bad design etc. of the electrical apparatus. Being able to pinpoint corona discharge and address potential equipment failure is important and can guarantee the reliable operation of the electrical ultraviolet (UV) cameras detect voltage related corona and arcing. Indeed, a combination of Infrared (IR) thermal sensors and Ultraviolet sensors is complementary and beneficial.

Ofil's corona cameras can direct maintenance engineers to the exact location of the failure, and cut sharply both direct inspection costs and indirect costs of un needed washing, un needed replacements, unexpected shutdown, extending parts lifetime, deferring aging processes.

why Ofil?

Ofil's corona cameras are made with proprietary UV filters and high sensitivity sensors. All systems are strictly tested for solar blindness and have CE certificates.

Ofil offers a wide range of products, with proven performance, and affordable tailored and off-the- shelf solutions to match the specific needs of its customers.

Ofil is engaged with ongoing research & develpment activities and keeps its corona cameras updated technologically.

Ofil enriches its customers with supportive educational projects, and assists them master UV inspection methodology and predictive maintenance.

Ofil is attentive to its customers and listens to their versatile changing needs. Customers' support is provided locally through Ofil's worldwide network of representatives.

Railway Catenary Diagnostics

Ofil's DayCor® Rail is a fully automatic inspection solutions for overhead catenary diagnostics. Rail generates a full report of corona and arcing events that are detected on conductors and insulators. The report is generated automatically at the end of a trip. Rail is a unique smart development by Ofil's R&D high level team. Available as tailor-made or as Commercial-Off-The-Shelf (COTS) product. (read more...)

the numbers

According to the USA Department of Energy, California lost 6.8% of total amount of electricity used in the state throughout that year valued about $2.4B.

Those losses are attributed to 2 major sources: resistive loss and corona loss. Corona does not spark across lines, but rather carry current (hence the loss) in the air along the wire.
