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.
Product Introduction
Digital double clamp Phase voltammeter is a high-precision low-price hand-held double-channel input measurement instrument designed for voltage current and Phase measurement on site.Using this meter the phase between u-u i-i and u-i can be easily measured in the field the phase sequence of sensitive and capacitive circuits and three-phase voltage can be distinguished the wiring group of transformers can be detected the secondary circuit and bus differential protection system can be tested the phase relationship between CT of each differential protection group can be read out and the wiring of the electricity meter can be checked.The tongs current transformer is used to input the measured current so there is no need to disconnect the measured line.When measuring the phase between u1-u2 the two input circuits are completely insulated and isolated so it completely avoids the possible short-circuit of the measured circuit caused by wrong wiring and thus burns out the measuring instrument.The display screen USES high-contrast Liquid crystal display with words up to 25mm and The screen Angle can be freely converted to about 70�° to obtain better visual effects.
Digital double clamp Phase voltammeter enclosure USES engineering insulation materials another rubber vibration protection sleeve safe and reliable.

High voltage insulation megohmmeter is composed of medium and large scale integrated circuits. This meter has large output power high short-circuit current value and large output voltage grades (there are four voltage grades). The working principle is as follows: the DC high voltage generated by the battery inside the machine as power supply and converted by DC/DC reaches the L pole from the E pole by the tested product so as to generate a current from E to L pole. After I/V conversion and operation by the divider the measured insulation resistance value is directly displayed by LCD.

The portable Three-phase standard power source is suitable for metering departments, power distribution terminals, power management, reactive power compensation devices and enterprise production.
Electrical equipments in modern industrial, commercial and residential users are more sensitive to power quality, and have a higher requirement of quality of power supply. Currently, harmonics,electromagnetic interference, power factor reduction have been tied to the three hazard of the power system.
When it is interfered or contaminated, grid power quality can t reach the national standards, so it has to be targeted on the grid power quality improvement. To understand the actual situation of power quality, you must have the appropriate equipment to test and analysis the actual situation. Counter the domestic condition, our company developed the professional power quality analysis instrument, which is suitable for the country.
