TKDL-II live cable identification instrument is used to identify A particular cable in the power cable setting migration maintenance and fault treatment to identify A cable in the cable. It has the characteristics of accurate fast simple operation and wide application. It is an indispensable testing instrument in cable construction and maintenance. The electric/uncharged cable recognition device USES single-chip microcomputer technology to encode and power the transmitting signal at the transmitting end which drives the large calibre calipers to coupling the signal to the live cable. The single chip in the receiver decodes and phase the received phase encoding signal. The target cable is identified from a large bundle of other cables based on the uniqueness of the signal phase characteristics on the target cable. It is a light compact compact lithium battery powered portable instrument. Suitable for all kinds of high and low voltage power cables.



1. Charged identification and un-charged identification function combined not only for identification and judgment of cable outage but also for the identification and judgment of live cables the operation is extremely simple very easy to use.

2. The instrument lithium battery-powered you can work continuously for 3 to 5 hours suitable for field use of passive field.

Overview

zinc oxide arrester tester is a special instrument used to test the electrical performance of zinc oxide arrester. The instrument is suitable for live or power failure detection of zinc oxide arrester of various voltage levels so as to timely detect the internal insulation damp and valve aging and other dangerous defects.



zinc oxide arrester tester is easy to operate and easy to use. The whole measuring process is controlled by single chip microcomputer. It can measure the total current resistive current and its harmonics power frequency reference voltage and its harmonics active power and phase difference. The instrument uses digital waveform analysis technology harmonic analysis and digital filtering software anti-interference methods to make the measurement results accurate and stable.

1. Full current measurement range: 0-10mA effective value 50Hz/60Hz accuracy: (reading 5% + 5a)

2. Measurement accuracy of resistive current fundamental wave (secondary method without Interphase Interference): (reading 5% + 5a)

3. Current harmonic accuracy: (reading 10% + 10a)

4. Reference voltage input range: 25V-250V RMS total harmonic content 30% 50Hz/60Hz

5. Reference voltage measurement accuracy: (reading 5% + 0.5V)

6. Voltage harmonic measurement accuracy: (reading 10%)

7. Angle between fundamental current and fundamental voltage: 0-360

8. Working time of battery: 6 hours of main engine charging power supply: 220 V 10% 50Hz/60Hz charging time: 5 hours

9. Host volume: 325 280 140
