The TDR2050 from Megger is a feature rich test instrument and as such may require a little familiarisation to get the most from your testing. This video, the first in a series of support videos for TDR, uses cable tap detection to explain the basic operation and use of the TDR2050. We hope this will be of some use to you. Please watch out for further videos in this series.

To ensure dependable operation even in the most demanding environments, the new DLRO100 instruments use novel circuitry that gives high noise immunity and guarantees stable readings. For physical protection they feature enclosures with an IP54 ingress protection rating even when the lid is open and testing is in progress.

Operator safety in adverse conditions is assured by a CAT IV 600 V safety rating in line with IEC61010. With and optional DC clamp, Dual-Ground operation is also supported. This greatly enhances safety when working in substations and similar environments by allowing tests to be carried out with both sides of the equipment under test grounded.

DLRO100 instruments have a wide range of applications, including checking the resistance of busbar and cable joints, measuring wire and cable resistance and verifying lightning conductor bonding. They are also well suited for testing switchgear and circuit breakers during manufacture and in the field, and they offer a smooth DC output that is particularly valuable for circuit breaker tests.
