Product Description

Introduction


Along with the low-voltage pulse reflectometry, our systems implement advanced high-voltage pre-location technologies that allow to determine the distance to faults of various types with a minimal harmful effect on the cable lines.High level of safety during the testing with our cable test vans and mobile systems is ensured by built-in protection against overcurrent, overvoltage and overheating, as well as by the use of a continuous grounding monitoring, vehicle door closure sensors and self-health check monitoring.
High speed sample system and high bandwidth input circuit are integrated in the tester to get the exact reflection curve of signal so that the distance of fault point to signal sample point can be calculated in high accuracy and high resolution Special sound location tester configuration can be applied to locate the fault point more exactly.
The cable fault tester is suitable for measuring power cables, high-frequency coaxial cables, local telephone cables, street lamp cables, low-resistance of short-circuit, open-circuit disconnection faults, and various materials of various materials with different cross-sections and different media. Leakage and high resistance flashover faults. A powerful cable management system that automatically generates test reports.
It can test a variety of 35KV under different voltage grade, different sections, different media and all kinds of material of power cable faults, including: open circuit, short circuit, low resistance, high resistance, high resistance leak flashover fault.
It can be any cable length measurement of radio wave propagation in the known speed.It can test the power cables buried path and buried depth.route tracing evaluation of electric lines and cables.

Basic operation
 

1. Basic steps:

1. Fault judgment
2. Fault distance testing
3. Route tracing
4. Pin-pointing

1. Fault judgment and test method chosen

1. When cable fault appeared, first determine the fault character as below:

• Test the phase to phase and phase-earth insulation resistance of one end of the cable by megger. If the result is zero, please use the multimeter to test the resistance.
• If the insulation resistance is very high but insulation is normal, please check whether open circuit fault exist. Here user can make three phases short circuit to the earth and test on the other end to distinguish.
• Fault character distinguish and test method form

 

No	Fault	Fault form	Distance test method	Pin-pointing method
1	Low resistance	Megger:0 Multimeter:< 200Ω	Low voltage impulse	Audio-frequency(optional)
				Audio magnetic synchronous
2	Open circuit	Conductor disconnection		Audio magnetic synchronous
3	High resistance	Megger:>0 Or: Megger:0 Multimeter:≥ 200Ω	Impulse current
4	Breakdown	Megger:insulation normal Withstand voltage test:no

Remark:

1. The gray part in the form means that, for these functions, extra matched high voltage generator is needed.
2. Audio-frequency method to pinpoint the low resistance is optional. This need the matched CD-1200T route tracing signal generator.
