“Time of Flight” partial discharge (PD) measurements are based upon the principle of time domain reflectometry (TDR)
Faults in cables can arise due to any defect, inconsistency, weakness, or non-homogeneity that affects the performance of the cable. Typically, faults are classified as:
Cable sheath faults are defects in the outer protective sheath of cables, such as PVC jackets.
Service faults in cables can occur due to many reasons, such as simple ageing of the insulation over time, sudden over-voltages, thermal overload, corrosion of the outside jacket, and poor workmanship during transport, instal
There is quite an array of solid insulation materials in the form of tape-bands, pressboards, films, laminates, etc. that can be used in a variety of equipment as electrical insulation.
Time domain reflectometry (TDR) is a simple and effective way to quickly locate faults, determine the length of a cable, or locate joints along a cable. The BAUR TDR 500 or TDR 510 are lightw
