Metering and Diagnostics
Introduction The purpose of this chapter is to provide detailed information regarding the
metering and diagnostic information that the E300 Electronic Overload Relay
generates. The metering and diagnostic functions are organized into seven
sections:
• Device Monitor
• Current Monitor
• Voltage Monitor
• Power Monitor
• Energy Monitor
• Trip/Warning History
• Trip Snapshot
Device Monitor The E300 Electronic Overload Relay's device monitor diagnostics provides
information on the status of the E300 Electronic Overload Relay which includes:
• Thermal overload protection
• Trip and warning protection functions
• Digital inputs and relay outputs
• Operator station
• Hardware options
• Time and date
Percent Thermal Capacity Utilized
Percent Thermal Capacity Utilized (Parameter 1) reports the calculated percent
thermal capacity utilization of the motor being monitored. When the percent
thermal capacity utilization equals 100%, the E300 Electronic Overload Relay
will issue an overload trip.
