WebOct 26, 2015 · The cable length can be measured by either a capacitive tester that's calibrated to the capacitive characteristics of the cable or with a Time Domain Reflectometer (TDR) tester. While both types can measure cable length, a TDR tester is more useful because it can measure the distance to a fault, a feature the capacitive tester lacks. WebJul 29, 2024 · Generally with high voltage systems (240v), we work out cable size on temperature rise, and then do a voltage drop check as an afterthought. On low voltage systems (12v), voltage drop tends to bite first. It's worth checking that any calculated cable is OK for temperature rise, but it's usually a no-brainer.
