SEL-701 Relay Monitoring & Reporting Features
In addition to the protection functions outlined earlier, the SEL-701 Relay offers
advanced measuring and monitoring capabilities not found in other motor relays,
including:
Extensive metering capabilities that provide real-time operating data.
Configurable front-panel display that replaces separate panel meters.
A load profiling function that records currents, voltages, and RTD
temperatures every 15 minutes for over 30 days.
Event and SER reports that offer detailed information about electrical
faults.
Motor start reporting that shows current, voltage, and thermal
element values through 60 seconds of motor start. Use this
information to validate transformer and cable sizing and confirm
motor starting simulations.
Motor start trending that shows average accelerating times, maximum
currents, and minimum voltages for each of the past eighteen 30-day
periods.
SEL
OGIC control equations that allow you to customize the operation
of contact inputs and outputs for your specific applications, if
necessary.
