Cable fault locator TDR-TA4.7

TDR-TA4.7 is intended for the following measurements on power cable lines:

cable length measurement and cable integrity tests;
measurement of the distance to the heterogeneity of the cable impedance or low-resistance fault, using TDR method;
measurement of the distance to the high-resistance fault, using the Arc Reflection Method (ARM) in complex with the high-voltage pulse generator (HVPG);
measurement of the distance to the high-resistance fault, using the Impulse Current Method (ICM) or Decay Method in complex with the high-voltage pulse generator (HVPG);
measurement of the velocity factor of the line at a known length.
