TDR Series

Efficient, accurate measurement of circuit-breaker dynamic timing and motion

Doble's TDR products allow you to test simple and complex circuit breakers using a single field-portable instrument and Windows-based software. Doble offers the following TDR instruments and software:

DFA100

The DFA100 Dielectric Fault Analyzer is a handheld, battery-powered instrument used for monitoring acoustic emissions. The acoustic emission diagnostic technique is a nonintrusive, in-service test for monitoring acoustic signals produced by partial discharge and loose components. The DFA100 is designed to detect faults in grounded SF₆ gas-insulated systems, such as SF₆-filled dead-tank circuit breakers. It can also be applied to grounded oil-filled instrument transformers.

TDR100

The TDR100 Circuit Breaker Test System is a simple, effective way to assess the condition of circuit breakers and switching devices. The TDR100 is a compact unit that provides quick and reliable results.

TDR900

The TDR900 Circuit Breaker Test System is a precision instrument for testing all types of circuit breakers. It performs timing functions for up to four breaks per phase with motion measurements.

T-Doble Software

Create and manage your circuit breaker test plans with software that combines the automatic control of the TDR test sets with the functionality of the DTAWeb database.

 "Everything You Want to Know about Breaker Testing"

October 6, 2010 at the Finepoint Conference in Pittsburgh, PA

Come learn everything you need to know about circuit breaker testing in this half-day seminar presented by Doble’s Jozef Levi and Joe Brown. The seminar will focus on three topics:

• Basic Design Characteristics of High Voltage Circuit Breakers
• Circuit Breaker Testing
• Analysis of Test Results

Attendees will receive an introduction to circuit breaker design and function which provides basic information for better test preparation and test results analysis. The seminar emphasizes the importance of good preparation for all stages of circuit breaker testing.
