The CTB-200 is produced to detect high frequency partial discharge in order to carry out the diagnosis of insulation of the facilities for power supply and distribution. It is designed to carry out diagnosis of the mold transformer, PT, CT, LBS, ASS, MOF and VCB at the boards for power supply and distribution at the stage of power distribution.
It has a comparatively high SNR compared with existing RFCT sensors, and, especially, the strong point is that it will not be saturated in tens of KA. Compared with Rogoski sensors, it has dozens of times higher sensitivity and SNR and is extremely good at reducing external noise. It is the main item for KESCO.
