Surge Protection For AC Rotating Machines

GEDigital EnergySurge Protection forAC Rotating MachinesCapacitors, TRANQUELL Arrestersand Motor Surge EquipmentProduct Selection & Application GuideGE Surge Protection Capacitors & EquipmentProtective capacitors offer surge protection for AC generators, synchronouscondensers and large motors. Surge capacitors protect the winding insulationby reducing the steepness of wave fronts applied to or reflected within themachine windings. Dielektrol is the GE non-PCB power capacitor dielectricfluid developed to provide an environmentally acceptable product with superiorperformance and reliability. GE protective capacitors contain an all film dielectricsystem and hermetically sealed bushings, which permit mounting thesecapacitors upright or on their side.GE TRANQUELL Arresters when utilized with GE Surge capacitors provideadditional security for AC rotating machines. Arresters provide a reductionof lightening stresses by limiting the amplitude of applied impulse waves orreflections within the machine windings.GE provides the complete assembly solution suitable for indoor or outdoorapplications. GE can also provide individual capacitor(s) and arresters forindividual application requirements.18L Series Protective Capacitors38F Series Motor Surge Protectiong

Application and Selection GuideSurge Capacitors & Motor Surge ProtectionApplication Guide – Protective CapacitorsApplication InformationFigure 1GE Dielektrol Surge Capacitors and TRANQUELL Motor Surge Protectors canbe applied directly at the motor or generator terminals to reduce the potentialfor damage caused by lightning and or switching surges.GE Surge Protective Capacitors reduce the steepness of wave fronts toprotect turn to turn insulation from surges applied to or reflected withinmachine windings.GE TRANQUELL Motor Surge Protectors utilize GE TRANQUELL Surge Arrestersapplied in parallel with GE Dielektrol Surge Capacitors. When applied together,the arresters protect the major insulation to ground by limiting the amplitudeof applied impulse waves or reflections within the machine windings, whilethe protective capacitor(s) reduce the steepness of the wave fronts. Studiesindicate that this dual protection approach results in significant reduction oflightning stresses imposed on rotating machines and contribute to increasedsecurity against failures and downtime costs. The enclosures are suitable forindoor and outdoor applications. (See Figure 1).TRANQUELL Motor Surge Protection Product Selection Process1. Determine the nominal system voltage and connection at the equipment being protected (Line-to Line, delta or wye, grounded or ungrounded).2.
