Under kW Trip Delay
Under kW Trip Delay (Parameter 379) allows you to define the time period an
under real power (kW) condition must be present before a trip occurs. It is
adjustable from 0.1…25.0 seconds.
Table 319 - Under kW Trip Delay (Parameter 379)
Under kW Trip Level
Under kW Trip Level (Parameter 380) allows you to define the real power (kW)
at which the E300 relay trips on an under real power (kW). It is user-adjustable
from 0…2,000,000 kW.
