5.7.4 Monitoring
In a typical monitoring application, several types of actions may be needed:
 Automatic action required: Monitoring the currents and voltages and the
system taking an immediate automatic action, like tripping a circuit breaker.
 Operator action required: Monitoring of the current temperature of gas in a
gas insulator around a circuit breaker. This could result in actions initiated by
an operator, such as sending maintenance people on-site.
 Post mortem analysis: Monitoring and collecting information about equipment
condition, to be analyzed by a specific tool, resulting in recommendations for
maintenance.
5.7.5 Measuring and Metering
Statistical evaluation of measured quantities, determining minimum and
maximum values over a period of time, and creating history of this information,
such as:
 currents, voltage, power and impedance in a three phase system (MMXU)
 calculation of energy in a three phase system (MMTR)
 calculation of harmonics and interharmonics (MHAI)
