OLTC Fault Detection Device
OFDR
OLTC (On Load Tap Changer) of power transformers monitors the secondary voltage during tap switching, utilizing algorithms that leverage big data to detect and diagnose various types of faults occurring during OLTC operation
  • Measure the electrical signals generated during OLTC tap switching to determine the condition of the tap connections
  • Continuously monitor the secondary voltage of the transformer to detect the degradation and integrity of the OLTC in real-time
  • Notify of faults and analyze the cause when an OLTC fault occurs
  • Remote monitoring, downloading, and analysis of fault data are possible through the Host Program
  • Compact in size with no need for separate panels, it can be installed directly onto the field transformer protection panel (Product size: 200mm x 130mm x 95mm)
