R-9 High-Surge Cable Fault Locator - Beijing Kanggaote Instruments and Equipment

Product introduction

The Ronaldo Cable Fault Locator manufactured by Beijing KGT is mainly composed of Ronaldo 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), multiple pulse(MIM) 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. 1800 J of surge energy provide the necessary power for accurately pinpointing cab

Product Features
■ Accurate fault localization: It utilizes 1800J of impact energy, providing clear
waveform feedback of the fault point.Utilizing a waveform sampling rate of up to
400MHz allows for waveform measurements that closely replicate the original waveform
and the waveform of each phase cable can be compared.
■ User-friendly: featuring an automatic mode, this device allows for one-key testing
using the low-voltage pulse method. The system automatically selects the appropriate
range and gain, providing direct fault distance localization.

Testing Standards
■ State Grid Equipment Distribution [2021] No. 86 Document Requirements (III)
Strengthen the con-figuration of testing equipment, further enhance the selection and
configuration of distribution cable operation and inspection equipment and online
monitoring devices, according to the distribution cable-specific operation and
inspection equipment configuration standards, categorize and classify the configuration
of AC withstand voltage, oscillating wave partial discharge, VLF testing & Tan Delta
diagnostics, cable path detection, cable identification, cable fault detection and
location equipment , and gradually promote the application of multifunctional,
lightweight, and intelligent live testing equipment.

Product Functions
The R-9 Cable Fault Locator manufactured by Beijing KGT is mainly composed of RHV-9 (High
Voltage) Generator and RTDR-9 Time Domain Reflectometer, including various Prelocation methods, such as low voltage pulse method, ICM (impulse current method ), ARM
measurement( Arc reflection method), multiple pulse(MIM) method.It can resolve the
malfunctions and locate the fault points, which contains low resistance, high resistance,
intermittent, flashover,leak ad disconnection fault on various cables of 380V, 6kV, 10kV, 35kV ,
110kV, 220kV.
RTDR-9 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.
1800 J of surge energy provide the necessary power for accurately pinpointing cable faults
with the acoustic method. Big wheels make the unit suitable for easy operation in the field.
Connecting cables for earthing, mains, and HV are conveniently accessible at the rear of the
unit.

Test Object
Power cables of 380V, 6kV, 10kV, 35kV, 110kV, 220kV.

Successful Cases
On April 20, 2023, we conducted a cable fault location for a 10 kV cable in Anyang and successfully located the fault point
accurately. The device identifified that the fault type is high resistance. The pin point was located 161 meters from the
beginning of the cable, and the fault point was finally found by combining the underground cable locator and the pin-pionter.
The test result was consistent with the R-9 test result.
