Cable reflectometers and bridges E'RSTED RI-407 STRIZH-S, TDR-109 STRIZH-S, etc.

Protected pulse reflectometer for power lines RI-407 "STRIZH-S"

RI-407 is a high–precision digital reflectometer specially designed to determine distances to any types of inhomogeneities and damages in power cable lines: breakage, short circuit, coupling, cable splice, parallel tap, cable locking.

Reflectometer RI-307USBm "STRIZH"

Pulse reflectometer RI‑307USBm is a two–channel cable locator designed to determine the nature and location of inhomogeneities and damage to the cable line (breakage, short circuit, coupling, cable splice, parallel tap, umbilical cord coil, broken pairs, "flickering" inhomogeneities).

Protected pulse reflectometer RI-307M3 "STRIZH"

The RI-307M3 reflectometer is a high–precision, field, 2-channel reflectometer for applications with increased requirements to the accuracy class (for example, SCS, in CATV networks, UEC systems of heating networks, etc.).The RI-307M3 allows the following measurements to be made with a low instrumental error (up to 3 cm) on cables from 1 m to 128 km long.

Protected pulse reflectometer-bridge RI-10M2 "STRIZH"

The pulse reflectometer RI-10M2 is a single–channel cable locator with a bridge measurement unit designed to determine the nature and location of inhomogeneities and damage to the cable line (breakage, short circuit, coupling, cable splice, parallel tap, umbilical cord coil, broken pairs), as well as to measure the basic parameters of cable lines by the bridge method (resistance of the loop, insulation resistance, cable capacitance measurement, core asymmetry, voltage, distance to leakage and breakage).

Protected pulse reflectometer RI-10M1 "STRIZH"

Pulse reflectometer RI-10M1 is a single–channel cable locator designed to determine the nature and location of inhomogeneities and damage to the cable line (breakage, short circuit, coupling, cable splice, parallel tap, umbilical cord coil, broken pairs).

Transitional device UP-1

UP-1 is a device used for galvanic isolation between the measuring connector of a pulse reflectometer and a cable line. UP-1 is compatible with the following devices: RI-10M1, RI-10M2, RI‑303T, RI-307, RI-307M3, RI-307USBm.

Reflectometer for power lines TDR-109 "STRIZH-S"

TDR-109 is a high–precision 3-channel digital reflectometer specially designed to determine distances to any types of inhomogeneities and damages in power cable lines: breakage, short circuit, coupling, cable splice, parallel tap, cable locking.

Reflectometer for power lines TDR-107 "STRIZH-S"

TDR-107 is a modern digital reflectometer specially designed for searching and diagnosing damages in power cable lines: breakage, short circuit, coupling, cable splice, parallel tap, cable locking, etc.
