Description
DTDR-100 Reflectometer
DTDR-100 is a high-class reflectometer with a sampling frequency of 400 MHz and a range of up to 100 km, which is designed to measure the total length of the cable and the distance to the place of damage of the cable with low transient resistance or wire break. Together with the high-voltage pulse generator HVIG-32 and the MIM MIMCU-32 connecting block, the DTDR-100 can also perform preliminary localization of high-resistance damaged power lines.
DTDR-100 is an easy-to-use and controllable device that, in addition to the touch screen, also supports button control, has a friendly interface and is used for preliminary localization of a damaged cable at a long distance.
- Sampling frequency 400 MHz.
- Low-voltage pulse method (TDR).

HVIG-32 High-voltage pulse generator
The high-voltage pulse generator HVIG-32 is used to provide a signal source for preliminary and accurate localization of the place of damage to the KL. Together with the DTDR-100 reflectometer and the MIM MIMCU-32 connection unit, it easily solves the following:
- Preliminary localization of damage by ICE and MIM methods.
- Detection of damaged KL by acoustic magnetic method with PP-4 receiver.
MIMCU-32 Connection block MIM
The MIM MIMCU-32 connection block is designed to work with the HVIG-32 high-voltage pulse generator and the DTDR-100 reflectometer for preliminary localization of damaged high resistance cables, including damage due to leakage, flash, low resistance and conductor breakage.
The MIMCU-32 is used to provide multi-pulse method (MIM) signal coupling for the DTDR-100 reflectometer. It uses a new MIM method to simplify the estimation of the shape of the cable damage signal. It can convert the complex form of the breakdown signal during voltage surges into a simple fault signal form that is easy to recognize.
- Provides the MIM function for preliminary localization.
- Impulse balancing technology: it is easy to distinguish the malfunction display.
- Simplicity in operation.
- Safe design.
- Isolation between measuring and OV circuits.
- Closed case without exposed OB components.
PP-4 Receiver
PP-4 is an easy-to-use device that is used to accurately determine the location of damage to the KL. It integrates the function of the acoustic method of magnetic synchronization, the method of determining the strength of the magnetic field to ensure accurate localization.
- Excellent acoustic quality and noise immunity.
- Intelligent acoustically magnetic method.
- Automatic mute function to protect your ears.
- Bright reflective display.
- Left/right cable indication.
CL-15/6 Pathfinder
CL-15/6 is a highly effective system for locating underground metal pipes. It consists of a transmitter and a receiver and can be used for tracing, investigating pipes and measuring the depth of underground cables and metal pipes. It can also be used to determine the cable from the bundle, to detect damaged pipe insulation and to close the grounding cable.
- Color compass for orientation.
