" ...We have implemented the DayCor® findings into maintenance repairs that have since paid for the cost of the camera in savings. The savings dollars would be derived from extending the life of line hardware, finding problems and repairing before failure on substation equipment and avoiding costly failures on higher voltage transmission line polymer insulators
The corona camera is a huge addition to the necessary equipment required to complete a proper power system inspection."

" ...We have two DayCor® cameras: one is mounted in a gimbal for helicopter use. The other is mounted on my van for land and foot patrols.
I am amazed at the durability of the camera. I have had it on top of my van, in a pan and tilt head, for extended periods and it has never failed to operate. It is a very well constructed inspection tool. The people at OFIL have done a wonderful job."

" ...The DayCor is most often used to find arcing on our distribution system (15kV and 25kV class systems).
Arcing on the distribution system causes interference with customer television and radio reception. In all instances, the DayCor has proven invaluable at pin-pointing the source of the interference (arcing location). Most often a cracked insulator, loose hardware, or a broken strand is identified. For this type of work, a DayCor is far superior to acoustic listening tools as a picture is more telling than locating the problem using sound.
EKPC is very pleased with the DayCor and Ofil. I am sure that you will find the DayCor to be a valuable tool and I would encourage you to join Ofil’s Users’ Group to gain knowledge on the use of the DayCor and to share your experiences with others."

" ...The DayCor has allowed us to replace a deteriorating insulator before it failed at our convenience and avoiding an unplanned outage.
We use the DayCor for routine monitoring of porcelain, glass and non ceramic insulators to check if our designs are corona free and if the insulators are still in good condition. Additionally, we have had good success finding corona problems in our substations using the camera. We have found the camera to be reliable, dependable and easy to use. Currently, it is our preferred method for finding corona on our system in the field and in our HV laboratory."
