It will not cause disturbances to sensitive networks or neighbouring equipment. Discharging the capacitors takes several seconds and tremendously limits the response time of such system. where 86 kvar are switched on by contactors. The current reaches 3640 A peak. less than 20ms for voltage drops compensation and instantaneous if an external signal is available. Limited life Contactors have limited lifetimes and need to be replaced frequently. Current waveform when switching a conventional bank with contactors (transient) Current waveform when switching a Dynacomp® Slow response time Electromechanically switched power factor correction systems are fitted with discharge resistors. approximately twelve times the nominal 304 A peak. This allows reducing the voltage difference between the capacitors and the network and consequently the magnitude of the transients. Fast response time The powerful control of the Dynacomp® and its switching concept allows dynamic response times less than 80ms for power factor correction. Long life The transient free switching (with no electric arc. Such systems also require important maintenance efforts. The disturbance created in the voltage waveform could perturb sensitive equipment. the nominal value. is the perfect choice in applications where transient-free switching is required. without suppressing the transients. but the precise instant of switching is variable and not controlled. This has the consequence that the switching of the capacitors results in a big transient. i.e. no moving parts) combined with the self healing capacitors used in the Dynacomp® guarantees a very long life of the system without any limitation in the number of switching operations.

Equipment that generate harmonics: • Fluorescent lighting systems • Welding equipment • Rectifiers • Microwave ovens • Computers • UPS • TV monitors The third harmonics are accumulated in the neutral conductor. In network: • • • • • • Overheating Increased power losses Poor quality of electricity Electromagnetic fields Malfunctions in earth fault control Failure in remote control systems In plants: • • • • • • • • • 9/14 1SDC007200C0202 Malfunction in electronics Damage to capacitors Power losses Increased magnetic fields Overload in neutral conductor Cable fires Abnormal temperature changes and noise in transformers Nuisance tripping in circuit-breakers Shorter life time . The third harmonic found in the phase current appears neutral thus increasing the neutral current. One reason for this is the increasing use of electric equipment that generate harmonics: in particular the third harmonic.a Growing Problem Today's electrical networks and plants are under much more stress than a decade ago. This harmonic can generate exceptionally high neutral currents which can often exceed even the phase current. The THF filter mitigates the third harmonic current from the whole network from the luminances to the distribution panel.The Third Harmonic Filter THFstar The third harmonic filter THFstar removes the third harmonic current from the network. 9/15 1SDC007200C0202 Network Quality .

The CT shall always measure the sum of all neutral and earth currents of the network. • Read mounting instruction 34THF1S • Check that there is no largely dimmer loads. Main incoming breaker: Max. For example the neutral current reduces from 450A down to 25A and in the phase conductors from 150A to 10A.1 W = 62. The magnetic field from the construction and earthing wiring reduces typically by 50% due to mitigation of the vagabonding currents ( 50% of magnetic field usually of 150 Hz origin).5 W The filter include protection unit. The neutral conductor from the star point of the transformer is the recommended place. The THFstar removes typically 95% of the third harmonic current from the whole network from line and load side independent of the magnitude of the third harmonic current. time delay: 0. The same mitigation prevails in the whole network from the transformer windings to the lamps and computers.
