Current Imbalance Trip Delay
Current Imbalance Trip Delay (Parameter 260) allows you to define the time
period a current imbalance condition must be present before a trip occurs. It is
adjustable from 0.1…25.0 s.
Table 259 - Current Imbalance Trip Delay (Parameter 260)
Current Imbalance Trip Level
Current Imbalance Trip Level (Parameter 261) allows you to define the
percentage at which the E300 relay trips on a current imbalance. It is user-
adjustable from 10…100%.
The Protection Fault State of Relay 0, Relay 1, Relay 2, Digital Module 1 Output
Relays, Digital Module 2 Output Relays, Digital Module 3 Output Relays, and
Digital Module 4 Output Relays are defined by the respective parameters:
• Output PT00 Protection Fault Action (Parameter 304)
• Output PT00 Protection Fault Value (Parameter 305)
• Output PT01 Protection Fault Action (Parameter 310)
• Output PT01 Protection Fault Value (Parameter 311)
• Output PT02 Protection Fault Action (Parameter 316)
• Output PT02 Protection Fault Value (Parameter 317)
• Output Digital Module 1 Protection Fault Action (Parameter 322)
• Output Digital Module 1 Protection Fault Value (Parameter 323)
• Output Digital Module 2 Protection Fault Action (Parameter 328)
