Circuit Breaker Diagnostics: Doble’s circuit breaker diagnostic products allow you to test simple and complex circuit breakers using a single field-portable instrument and Windows-based software.
 
TDR900 Circuit Breaker Test System: Perform timing functions for up to 4 breaks per phase with motion The TDR900 Circuit Breaker Test System is a precision instrument for testing all types of circuit breakers. It detects main contact and resistor switch timing errors for up to four breaks per phase with motion measurements, at a resolution of 100 μs.
 
T-Doble Software: The TDR900 comes with T-Doble software for improved data management capability. With intuitive T-Doble software, you can:

Make and compare breaker timing measurements.
Create easy-to-use test plans and view test results.
Plot, overlay, analyze, and print data. 
Import TDR9000 and TR3100 test result data and test plans.
 
Features and Benefits
High-accuracy motion recording. Patented digital rotary/linear transducer provides early diagnosis of mechanical problems and auxiliary switch and main contact timing errors.
 
Immune to interference. Accuracy of test results is unaffected by electrostatic and     electromagnetic interference in substation environments.
 
Rugged and reliable. Single-box solution provides the accuracy of a laboratory instrument with durability for field use.
 
User-friendly PC interface. Intuitive software control panel on your PC permits quick, efficient testing.
 
Dielectric Fault Analyzer DFA100: The DFA100 Dielectric Fault Analyzer is a handheld, battery-powered instrument for monitoring non-intrusive, in-service 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. The DFA100 can also be applied to grounded oil-filled instrument transformers.
 
You can apply the DFA100 to any grounded component associated with the SF6-filled apparatus under test. During acoustic emission measurement, the DFA100 processes the results and determines the fault. The instrument can differentiate between PD, particles, and mechanical defects.
 
Doble M5000 Series: Doble’s M5000 series uses sweep frequency response analysis to detect mechanical failure or movement of windings from short circuits, mechanical stresses, or transportation. The instruments send an excitation signal into the transformer and measure the returning signals. Comparing this response to baseline and other results (such as from similar units) allows you to identify deviations and confirm internal mechanical problems.
