E.2 Type testing of the interface protection
E.2.1 General
If the interface protection is considered as a dedicated device external to the micro-generator, only the operate time
of the interface protection can be evaluated. In this case, the opening time of the interface switch shall be taken into
account when evaluating the compliance with this European Standard.

P
EUT
: EUT output power
2)
PAC: Real power flow at S1 as in Figure 1. Positive value means the power from EUT to utility. Nominal value is the 0% test condition value.
3)
QAC: Reactive power flow at S1 as in Figure 1. Positive value means the power from EUT to utility. Nominal value is the 0% test condition
value
4)
BL: Balance condition, IB: Imbalance condition
*: Needs to be measured if any of the recorded run-on times at imbalanced condition are longer than the one recorded for the rated balance
condition at test condition A
** “Run on time” must be < 2s
The filled out switch-off time values the highest among the three phase
