Product Description

Introduction


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 RCI-700T Integrated Power Cable Fault Tester is an intelligent power cable fault tester.
It has integrated functions as:

1. Fault locating
2. Pin-pointing
3. Basic route tracing

RCI-700T includes two main devices and the accessories

The function of the two devices:

1. RCI-700TM Integrated Power Cable Fault Tester

• Low voltage impulse fault distance testing
• Impulse current fault distance testing
• Audio magnetic synchronous pin-pointing
• Route tracing

1. RCI-700TT Route Tracing Signal Generator

• Transmit signal for route tracing

Compared with the traditional single functional device, the RCI-700T is portable with small size and low weight. It is an upgrade device in locating area.

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.
