Fault Record
The Fault Record contains the last 32 faults. The Fault Record displays one fault at a time and includes the following
information:
•
Record number
•
Fault number
•
Reclose sequence number and enabled
settings table
•
Date and time
•
Tripping element
•
Apparent distance to the fault in miles
•
Fault resistance
•
Relay operate time
•
Breaker clearing time
•
Phase and neutral currents (magnitude and angle)
•
Positive, negative and zero sequence currents (magnitude and angle)
•
Phase voltages (magnitude and angle)
•
Positive and negative sequence voltages (magnitude and angle)
Save the Fault Record as a file by using WinECP.
Operations Record
The DPU1500R provides an operations log in which any operation within the DPU1500R is recorded. This includes
internal operations such as logical tripping elements and relay failures. The operations recorder also logs external
events such as settings changes, circuit breaker operations, and logical input operations. During a fault the operations
recorder does not know or care what element actually tripped and cleared the fault. It only knows that certain logical
element became active and logs them with a time stamp. It is very possible that many elements may be logged for a
specific fault but only one was responsible for fault clearing. See the Fault Records for the element responsible for fault
clearing. A complete listing of all the possible operations logs is listed along with a description in Table 7-2. For
detailed definitions to the actual logical elements 51P (3I>), 27-1P (U<), see the Programmable Outputs Section. It is
important to note that the operations record logs only those elements that change state.
