The thermal meter function also reports the state
of connected RTDs if any have failed. Failure
messages are:
Table 8.5 RTD Input Status Messages
8.1.6 Energy Metering
Table 8.6 Energy Meter Values
When voltage inputs are selected and connected,
the relay records the real, reactive, and apparent
energy consumed by the motor.
8.2 Power Measurement
Conventions
The SIMPRO-100 Relay uses the IEEE
convention for power measurement assuming
motor action. The implications of this convention
are described by Table 8.1.
Figure 8.1 Power Measurement Conventions
In the SIMPRO-100 Relay, reported positive real
power and energy are always into the motor.
