Protective Trip and Warning Functions Chapter 5
Table 91 - Current Imbalance Trip Level (Parameter 261)
Current Imbalance Warning
The E300 Electronic Overload Relay will indicate a current imbalance warning
if:
• No warning currently exists
• Current Imbalance Warning is enabled
• Current is present
• Current Imbalance Inhibit Time has expired
• The current imbalance (parameter 52) is greater than the Current
Im
balance Warning Level
When the Current Imbalance Warning conditions are satisfied, the:
• T
RIP/WARN LED will flash a yellow 7-short blink pattern
• Bit 6 in Current Warning Status (Parameter 10) will set to 1
• Bit 1 in Device Status 0 (Parameter 20) will set to 1
• Any relay outputs configured as a Warning Alarm will close
Current Imbalance Warning Level
Current Imbalance Warning Level (Parameter 262) allows the user to define the
percentage at which the E300 Electronic Overload Relay will indicate a warning.
It is user-adjustable from 10…100%.
Default Value 35
Minimum Value 10
Maximum Value 100
Parameter Type USINT
Size (Bytes) 1
Scaling Factor 1
Units %
IMPORTANT
The Current Imbalance Inhibit Timer starts after a phase of load current
transitions from 0A to 30% of the device’s minimum FLA setting. The E300
Electronic Overload Relay does not begin monitoring for a current imbalance
condition until the Current Imbalance Inhibit Time expires.
