Product Description
Portable Laser Insulator Flaw Locating Faults Detector
I. General Information
In High Voltage Distribution Network, it usually cause the faults of flashover, grounding or porcelain explosion because of insulators degradation. So it is important to detect and eliminate the faults of insulators, to ensure safe running of transmission and distribution line.
The model GD-610 is used to detect faults of insulators and locate the faults in power station, substation without cutting power. It also can be used for PD detection, corona discharge detection, Discharge detection of electric equipment.
Detection Items is as following,
1.Unknown flashover fault of live insulators (trip and switch on for many times)
2.Leak current to the ground of live insulators (responsible sensitivity is no less than 1mA)
3.Composite fault of insulators.
4.Oxidation discharge detection of HV connectors.
5.Bad contact discharge detection of HV equipment.
6.Corona discharge detection.
7.Pollution flashover detection.
II. Work Principle
When the insulators have faults because of degradation, it will generate high-frequency ultrasound. Human can not hear it.
The model GD-610 will receive and enlarge this sound and it will be handled by special microcomputer. The small signal will be converted to audio signal and it can be heard by human through earphone. The LCD screen will also show the indicator of sound, to judge the degradation degree of insulators. The fault position is located by laser.
III. Features
1. Far distance detection, laser aiming, which locate the degradation insulators accurately.
2. Aluminum frame, robust and light weight.
3. With stereo headphone and LCD screen.
4. Strong interference ability.
5. With data lock function, under-voltage function(If low voltage, the instrument will shut off automatically). It is charged by constant current and stops by itself after full charge.
6. Lithium battery for 1000times charging.
7. With sound indication, safe and reliable, easy operation.
