简介
GDGZ-1828 cable fault tester Overview:
GDGZ1828 cable fault tester is a comprehensive set of cable fault testing system is integrated cable fault location system. It can be measured 0 ~ 35KV different voltage levels power cables, communication cables, signal cables and other types of cables and types can test out the point of failure, such as: ground fault, leakage cable fault, mixed line failure, disconnection and other failures types of faults. GDGZ-1828 cable fault tester is GDGZ-1826 cable fault tester, GDGZ-1829 Cable Fault Power, GDGZ-1827 cable fault locator composition, this powerful combination, carrying very aspects of transport.
GDGZ-1828 cable fault tester Main features:
1, GDGZ-1828 cable fault tester two methods of work:
① low pressure pulse method: for precise distance measuring low resistance, short-circuit, wire break, but also for a total length of cable and the middle joint, T-joint, measurement terminal head, and correcting wave velocity. Cable fault and waveform at right:
② Pulse Current law: for high resistance, the distance measurement flashover type of failure, the use of current coupler to acquire signals from the test line, and GDGZ-1828 in combination with the power cable fault testing before realizing pulse current method, and its complete isolation, safe and reliable. Test cable fault waveform at right:
2, high precision
The instrument uses high-speed data sampling technology, A / D sampling rate of 100MHz, instrument reading resolution of 1m, blind spot detection to 1m;
3, the high degree of intelligence
Test results are automatically displayed on the large-screen LCD display, intuitive to determine the fault and waveform data; and with a full Chinese menu display operation function, without the need for special operator training;
3, has a waveform and parameter storage and recall function;
4, the use of non-volatile devices, shut down after the waveform data is not easy to lose;
5, having dual trace display function;
6, the cable fault test waveform with the normal waveform comparison, is conducive to further determine the fault;
7, with the ratio of the waveform extend function;
8, the ratio change waveform, scalable waveform accurate testing;
9, can be arbitrarily change the position of the cursor dual, or directly from the relative distance to the fault point and test point is displayed directly;
10, depending on the cable under test has the right to modify the propagation speed function;
Small size portable form factor, built-in rechargeable battery-powered, easy to carry and use
GDGZ-1828 Cable Fault Tester Features:
1, complete the general high impedance, pinpoint network type flash point of failure.
2, find the location of the cable (path), probing the cable burial depth, identify the specific cable.
3, metallic breakdown (dead ground), using a magnetic field measurements pinpoint.
