[Harmonic Wave Diagnostic Device Example] Cable Diagnosis
Measured with a high harmonic sensor! A case where signs of insulation abnormalities were observed in the power plant system cables.
We would like to introduce a case of cable diagnosis conducted using our harmonic diagnostic device. The measurement locations were the high-voltage substation side (IN side) and the substation side (OUT side). Each phase of the cable's IN side and OUT side was measured using a harmonic sensor. A total of six measurements were conducted in AC motor mode. The diagnosis revealed signs of insulation abnormalities in the power building system's cable. Furthermore, it was noted that if the issues can be resolved in the future, this diagnosis would be advantageous. 【Case Overview】 ■ Measurement Locations: High-voltage substation side (IN side), substation side (OUT side) ■ Measurement Method: Each phase of the cable's IN side and OUT side was measured using a harmonic sensor ■ Results - Abnormalities were observed in the power building system's cable - Attention is required regarding the power building cable (T phase) *For more details, please refer to the PDF document or feel free to contact us.
