EM720 Power Quality and Revenue Meter
For the remaining characteristics of the voltage, by their
unpredictable nature, the standard gives only indicative
values, which are
information on the order of magnitude which can be
expected.
The following table gives the characteristics for which
indicative values have been specified by the standard.
Voltage Characteristic
Voltage dips
Short interruptions
Long interruptions
Temporary overvoltages
Transient overvoltages
