Meter parameters of transmission lines P5-10
|
Meter parameter transmission lines & nbsp; P5-10 & nbsp; designed to detect the wave resistance nonuniformity (damage) in the cables and power lines and communication in coaxial radiofrequency paths, for determining the distance (time delay) to the fault (heterogeneity), the nature of damage measuring the magnitude inhomogeneity.
P5-10 device can be used in the field and the laboratory for measurements on damaged lines and cables to monitor status, fault forecasting them, measure their lengths and by balancing the time delay with high accuracy .
The principle of operation P5-10 device is based on the method of pulse reflectometry & nbsp; & mdash; modern methods of investigation of distributed systems, allows us to observe simultaneously all the irregularities in the line and measure the position and characteristics of each of them individually .
The main advantages of the method is a good representation of the measurement results, m aloe time measurement, high sensitivity, the possibility of determining the parameters of a distributed system elements in ohms, Henry Farads.
Modern meters parameters inhomogeneities transmission lines picosecond range are characterized by high resolution in distance constituting units of centimeters (for the lines with air . filling)
