Protective Trip and Warning Functions
Chapter 6
Reactive Power (kVAR) Protection
The E300 Electronic Overload Relay has the capability to help protect against
reactive power (kVAR) for specific applications that require the monitoring of
both voltage and current. You can help protect or issue a warning if the reactive
power (kVAR) of an electric motor is either too high or too low.
Under kVAR Consumed Inhibit Time
Under kVAR Consumed Inhibit Time (Parameter 386) allows you to inhibit an
under reactive power (kVAR) consumed trip and warning from occurring during
the motor starting sequence. It is adjustable from 0…250 seconds.
Table 260 - Under kVAR Consumed Inhibit Time (Parameter 386)
Over kVAR Consumed Inhibit Time
Over kVAR Consumed Inhibit Time (Parameter 390) allows you to inhibit an
over reactive power (kVAR) consumed trip and warning from occurring during
the motor starting sequence. It is adjustable from 0…250 seconds.
Table 261 - Over kVAR Consumed Inhibit Time (Parameter 390)
IMPORTANT
The Over kW Warning function does not include a time delay feature. Once the
Over kW Inhibit Time has expired, the Over kW Warning indication is
instantaneous.
