TDR.950A Time Domain Reflectometer
Introduction to the TDR.950A:
TDR Low current impulse method: apply to the locating of the low resistance fault. Short circuit fault, open circuit fault. It also can be used in the measurement of the cable length, the intermediate joints, T joints, and cable termination joint.
ICM/Decay Impulse current method: apply to the high resistance fault, breakdown fault. Use the current coupler to gather signal from the earth wire, it allows the user to be a safe distance from the high voltage source.
ARM Arc reflection method complete with coupler
• Light, compact and easy to operate
• Main unit for the tried-and-tested pre-location method
• Compliant with the following standards GB/T 18268,1, DL/T849,1-2019 & JJF1042-2020.
