3. A field indicating the duration, expressed in number of cycles, for Voltage Sags/Dips and Swells
and for Current Peaks; it ill be zero for all other events.
4. A peak value indicating the maximum value attained by the parameter during the event; its
representation is user configurable in the configuration file (DOUBLEWORD or FLOAT IEEE754).

The terms used are those contemplated by the IEEE 1159 standards.
