R-15
Product characteristics
High precision: The cable defect positioning results are accurate and reliable, with an error less than 0.1%.
Fast detection: The detection speed is fast, no damage to the cable, can shorten the power outagemaintenance time, and minimize the impact of power outage.
Test without blind spot: The device can locate short cable faults and defects without test blind spots and can test the fault of unarmored cables, with better field applicability.
Light and portable: Using linear cable parameters, dielectric constant impedance measuremen support three-phase test and the same screen comparison.
Product function
R-15 cable wideband impedance analyzer can locate faults in power cables and communication cables of any voltage level, such as over-short circuit (trip) break (power off),partial discharge (spark)
It can also locate cable defects, such as local thermal aging, water moisture, overheating, radiation, wa
ter tree intrusion, electric tree intrusion, external damage、cable breakdown.
The fault types of motor winding (inter-turn short circuit,winding loosening, local thermal aging, end creepage,fracture of pressure equalizing coating, etc.) can be judged
