Protective Trip and Warning Functions Chapter 6
• No trip currently exists
• Under kVA Trip is enabled
• Current is present
• Voltage is present
• Under kVA Inhibit Time has expired
• The total apparent power (kVA) is less than the Under kVA Trip Level for
a
ti
me period greater than the Under kVA Trip Delay.
If the E300 relay trips on an under apparent power (kVA), the:
• TRIP/WARN LED status indicator flashes a red 2-long / 7-short blink
patter
n
• B
it 6 in Power Trip Status (Parameter 6) sets to 1
• Bit 0 in Device Status 0 (Parameter 20) sets to 1
• Any relay outputs configured as a Trip Relay open
• Any relay outputs configured as a Control Relay open
• Any relay outputs configured as a Trip Alarm close
• Any relay outputs configured as a Normal Relay are placed in their
Prote
ction Fault state (if so programmed)
Under kVA Trip Delay
Under kVA Trip Delay (Parameter 403) allows you to define the time period an
under apparent power (kVA) condition must be present before a trip occurs. It is
adjustable from 0.1…25.0 seconds.
IMPORTANT
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)
• Output Digital Module 2 Protection Fault Value (Parameter 329)
• Output Digital Module 3 Protection Fault Action (Parameter 334)
• Output Digital Module 3 Protection Fault Value (Parameter 335)
• Output Digital Module 4 Protection Fault Action (Parameter 340)
• Output Digital Module 4 Protection Fault Value (Parameter 342)
