5.2.2.2 Steady state voltage and current limits

ES1:

(1) d.c. : ES1<60V or 2mA

(2) a.c up to 1 kHz : ES1<42.4Vpeak or 0.707mApeak; ES1<30Vr.m.s. or 0.5 mAr.m.s

- not exceeding ES2 limits under single fault conditions of a basicsafeguard or of a supplementary safeguard.

比如：2个Y电容串联，短路1个Y电容。

ES2:

(1) d.c. : 60V and2mA<ES2<120V or 25mA

(2) a.c up to 1 kHz : 42.4Vpeak and 0.707mApeak<ES2<70.7Vpeakor 7.07mApeak; 30Vr.m.s. and 0.5mAr.m.s<ES2<50Vr.m.s. or 5mAr.m.s.

Peak values shall be used for non-sinusoidal voltage and current. RMSvalues may be used only for sinusoidal voltage and current.

总结： ES1 ES2 ES3

↓ ↓ ↓

AC： 42.4V——70.7V

0.707mA——7.07mA

30V r.m.s——50V r.m.s

DC： 60V——120V

2mA——25mA
