Voltage Imbalance Trip Level
Voltage Imbalance Trip Level (Parameter 367) allows you to define the
percentage at which the E300 Electronic Overload Relay trips on a voltage
imbalance. It is user-adjustable from 10…100%.
Table 235 - Voltage Imbalance Trip Level (Parameter 367)
Voltage Imbalance Warning
The E300 Electronic Overload Relay indicates a voltage imbalance warning if:
•
No warning currently exists
•
Voltage Imbalance Warning is enabled
•
Voltage is present
•
Voltage Imbalance Inhibit Time has expired
•
The Voltage Imbalance (Parameter 61) is greater than the Voltage
Imbalance Warning Level
When the Voltage Imbalance Warning conditions are satisfied, the:
•
TRIP/WARN LED flashes a yellow red 1-long / 3-short blink pattern
•
Bit 2 in Voltage Warning Status (Parameter 11) sets to 1
•
Bit 1 in Device Status 0 (Parameter 20) sets to 1
•
Any relay outputs configured as a Warning Alarm close

IMPORTANT
The Voltage Imbalance Inhibit Timer starts after a phase voltage transitions
from 0V to 20V L-L. The E300 Electronic Overload Relay does not begin
monitoring for a voltage imbalance condition until the Voltage Imbalance
Inhibit Time expires.
