Measuring R5-10 inhomogeneities lines (R510, R5 10, p5-10, p5 10, p510)
Measuring R5-10 inhomogeneities lines (R 5-10/1) is a versatile compact device with replaceable power supplies, providing work from a DC voltage from 10V to 15V and 22V to 30V, AC voltage (220 ± 22) frequency of 50 400 Hz and an autonomous power source. The device can work in the field at a temperature of minus 30 to plus 50 ° C and relative humidity 98% at temperatures up to 35 ° C.
Meters R5-10 are designed to perform the following operations on the overhead and cable power lines and communication: fault detection and determination of his character (open circuit, short-circuit), the detection of heterogeneity concentrated impedance (asymmetry in the wires break in the connection, insert, heterogeneity of dramatic change insulation resistance, etc.) to determine the distance to the fault or discontinuities.
Meter R5-10 can be used not only for measurements on damaged lines, but also for monitoring cables predicting faults in them, measure their lengths and balancing.
P5 equiv meter 10 provides a view of lines to 80 dB attenuation in the frequency band from 3.5 kHz to 7 MHz.
The minimum length of the line from which you can view, does not exceed 5 meters, but can be minimized by connecting the line to the top of the calibrated insertion length of the order of 4-5 m with the same characteristic impedance.
