OCB Module |
The OCB module measures the timing of main contact and resistor switches during closing or opening of an OCB Circuit Breaker. This module also measures the value of pre-insertion resistors, if the resistance value option is present.

100 μs |
Contact Bounce Measurement Programmable 4-100ms: |
60 μs Default |
Resistor Value Range |
10-400 Ohms or 300 - 7000 Ohms |
Resistor Value Measurement Accuracy |
± 10 % of measured value |
Resistor Tabulation Qualifier |
100 μs - 200 μs |
Motion Module |
The Motion module records the motion of the Circuit Breaker mechanism through a Doble Digital Rotary or Linear Transducer. The input connection for the digital transducer to TDR9000 is through a 25-pin "D" connector.

Number Of Motion Recording Channels: |
optionally 3 or 6 |
EHV Module |
The EHV module measures timing of main contacts and resistor switches during closing or opening of an EHV Circuit Breaker. It measures two breaks per phase for threephases of the breaker. This module also measures the value of Pre-Insertion Resistors if the resistance value option is present.
