APPLICATIONS
surge suppressors designed protect windings electrical machines transformers against steep fronted high voltage impulses which occur result atmospheric discharges. reduce power-frequency voltages which transferred capacitively secondary tertiary side transformers event earth fault occuring primary side.
CURRENT-CARRYING CAPACITY
surge suppressors installed systems with insulated neutral earthed through arc-suppressions coils systems with rigidly earthed neutral loaded continuously rated voltage used frequencies surge suppressors meet insulation requirements equipment rated above (VDE 0111/12.66).
CONSTRUCTION
surge suppressors have either indoor outdoor bushings. Their active parts flat-type winding elements with electrodes which insulated from each other. winding elements incorporated into capacitor casing. Both moisture extracted under vacuum high temperature cavities filled with impregnant. capacitor casings either aluminum stainless steel given coatings paint. Capacitors rated voltages form basic units. Those have bushings. Capacitors above have bushing second pole connected casing. Capacitors used systems with voltage higher than mounted base insulators, with maximum capacitors connected series same insulator.

According 0111, paragraph system effectively earthed event simple earth fault, voltage healthy phases cannot exceed system (phase-to-phase) voltage. transformer neutral points system need earthed achieve this. cases doubt, recommended choose capacitors whose rated voltage equal system voltage.

Protection Against Steep-Fronted Voltage Impulses Electrical machines connected overhead lines without cables transformers being interposed should protected capacitors (VDE 0675 Guidelines Surge Suppression Equipment). These surge suppressors connected inter-turn faults. Because their energy storing capability, surge suppressors reduce front steepness voltage impulses (see Fig. This flattering effect also avoids damaging impulse reflections equipment connected. Moreover, magnitude overvoltage also reduced since impulse entering winding finite `virtual time half value tail'. capacitances stated above table have been calculated that front steepness voltage impulse entering winding reduced maximum winding test voltage

Description
Vishay ESTA
Surge arresters used conjunction with surge suppressor capacitors operates lower instantaneous value voltage than without such capacitors. This because reduced front steepness impulse consequently lessened effect `delayed ignition'. obvious advantage that machine windings, which most cases have weaker insulation than overhead lines, better protected. machine arresters must, therefore, designed lower impulse power-frequency sparkover voltages than usual arresters. other hand, since they likely operate event internal overvoltages well, they must have correspondingly higher discharge capacity. case electrical equipment connected overhead lines through cables, capacitance surge suppressor capacitance reduced roughly amount corresponding operating cables. inductance's capacitance's machines transformers connected have little influence size protective capacitance's required, inquires need therefore only made zone ahead equipment protected subject special conditions.
PROTECTION AGAINST POWER-FREQUENCY VOLTAGES TRANSFERRED CAPACITIVELY
case unloaded generator transformer with high transformation ratio (e.g. higher voltage side), unduly high power-frequency voltages transferred capacitively lower-voltage side (U2C) earth fault occurs higher-voltage side. single-phase earth fault, this expressed follows:

Whereas rigidly earthed systems under most favourable conditions:
thus seen that incoming impulse with peak 1000 virtual time half value tail (Tr) reduced peak capacitor. Moreover, voltage impulse terminal does attain maximum until time This shows that steepness incoming impulse been reduced considerably.

Zinc Oxide RC-Surge Suppressor (ZORC) HV-Motor Transformers M-Type Panel Mounting P-Type
DESCRIPTION
ZORC's surge suppressors with included varistors. technology design ZORC's same other capacitors this catalogue. ZORC's will protect transformers motors from insulation failures. surge transients will removed source ZORC's. lifetime transformers motors will increased many years. ZORC's will inside curves defined IEEE CIRGRe motor impulse withstand levels. reach comprehensive insulation coordination, independent what switching device switching curve used (air, vacuum, oil). ZORC's help reduce costs down time losses transformers motors replacements. ZORC's will reduce significant expenses maintenance insulation failures motors transformers, which user accept normal. ZORC's will eliminate connected with vacuum other switchgears, multiple striking (re- pre-) transients. ZORC's prevents high frequency currents zero contact switch.
