Description

The R-11 Cable Fault Locator is mainly composed of R-11
HV (High Voltage) Generator and TDR-RT Time Domain Reflectometer, including various
Pre-location methods, such as low voltage pulse method, ICM (impulse current method ), ARM
measurement( Arc reflection method), X-axis method auxiliary locating method. It can resolve
the malfunctions and locate the fault points, which contains low resistance, high resistance,
intermittent, flashover,leak and disconnection fault on various cables of 380V, 6KV, 10KV, 35KV,
110KV, 220kV.
TDR-RT reflection method can locate disconnected and low resistance faults, which is also able
to measure the full length of the cable or correct the wave speed. Big wheels make it easy for
customer to use at any site.
