Advisor: Dr. Zhan Sponsor: Oncor Electric Delivery
Development Team
Current Operation: a fault occurs and circuit breaker trips to protect equipment
Scenario: circuit breaker fails to operate and the transmission system goes unprotected and customers ultimately lose power
Background
Attach the CBM09 to a substation circuit breaker
Monitor trip signals to check for faults Relay information to control house and
technician
Objective
Reduce:• Maintenance time• Outage time• Costs
Provide: • Operation data to technician• Fault information to control house• Innovation
Justification
Project DesignProblem Statement, Functional Requirements, Conceptual Diagram, & Functional Diagram
Problem Statement
Problem: difficult to diagnose problems with circuit breakers when they fail
Need: problems with circuit breakers need to be recognized quickly and accurately
Solution: monitor circuit breaker and electronically report specific problems with it
Monitor:
1) Status of the trip coil
2) Trip signatures: Abnormal trip and slow trip
3) Re-strike of the circuit breaker
4) DC ripple
Functional Requirements(1 of 3)
User Selectable Parameters:
5) DC voltage: 125V or 48V
6) 3 or 5 cycle trip time: Time for slow trip
7) Sensitivity: Percent difference from reference
8) Primary Current: Trigger end of wave capture
9) Record Signature: Capture initial waveform
Functional Requirements (2 of 3)
Other requirements:
10) Store data log of breaker trip waveforms
11) Software for viewing the stored waveforms/data log
12) Communication ports capable of communicating RS-485 and RS-232 for data collection
13) Size: should not exceed 10” X 8” X 3”
14) Operational temperature range: -20°C to 85°C
