Harmonic analysis is a process of trapping time domain events in frequency domain. In industrial power distribution systems, control compulsions have necessitated increased usage of electronics. This has resulted in distortion of currents & voltages. These distortions can cause a variety of operational difficulties to often loads connected to the system. This analysis helps splitting the distortions into a set of sinusoidal waveforms. The resulting spectrum enables identifying content & severity of harmonics in the system. Advanced data processing algorithms are used for interpreting results to identify the root cause of the difficulties faced by the user.

Harmonic Balancer Installers is used to remove the balancer without damage to the balancer itself, the crankshaft or the position sensor. It removes the harmonic balancer on late model 3300 and 3800 V6 GMs requires pulling hardware much different than conventional pullers. The 45300 is equipped with the special bolts and adapters to pull the harmonic balancer cleanly without damage to the crank sensor. The tool comprises an elongated threaded shaft which includes a removable threaded adapter for attaching the shaft to the end of the crankshaft by means of an axial threaded hole in the crankshaft end. A bolt connects the threaded adapter to the shaft, and a thrust bearing slidably mounted upon the shaft is axially forced into engagement with the balancer by a shaft mounted nut whereby rotation of the nut forces the thrust bearing against the balancer pushing the balancer upon the crankshaft. The use of adapters having various sizes and thread specifications permits the tool to be employed with a wide variety of crankshaft sizes and models.

Harmonic Balancer Pullers allows the removing of Chrysler and damper pulleys in tight engine compartments without removing the radiator. It removes and installs the harmonic balancer on most popular Chrysler, Hyundai, and Mazda without removing the radiator. It includes puller body, pin set and holding ring. It is packaged in a blow molded case with laminated instruction cards or stickers integrated into case design for handy reference of application information. It contains the there-jaw puller, three lengths of forcing rods, and a forcing screw with a 3/8″ square drive for ratchet use.

Harmonic filter banks are designed for industrial, utility, and commercial power systems to improve power factor, reduce harmonic distortion, increase system capacity, and improve voltage regulation. These are available in both indoor and outdoor designs with a host of options and accessories to fit the requirements and desired configurations of virtually all installations.

Harmonic Filter Inductors are used for isolating harmonic current to protect electrical equipment from damage due to harmonic voltage distortion. They can also be used to improve power factor. Harmonic filter inductors range from small single or three phase, low voltage units to large single-phase devices typically used in medium voltage applications. Although the low voltage devices have typical standard sizes, medium voltage units are usually designed to a specific application and hence are customized products. Harmonic Filter Inductors are also referred to as harmonic filter reactors or tuning reactors. Harmonic filter inductors differ from other types of magnetic devices inductors, reactors or chokes in their design and construction characteristics. The harmonic filter inductor has amongst its design characteristics a large consideration for harmonic currents. It is not uncommon to have harmonic current ratings greater than the fundamental 60 Hz current rating. This high harmonic content will create additional heating in the magnetic device. Harmonic filter inductors are compensated in the winding, gap and core losses for their specified harmonic contents.

Multi-step capacitor banks provide accurate control of power factor from light load conditions through heavy load conditions. It not only improves power factor, significantly reducing energy bills, but also removes reactive current from a power distribution system. This provides additional usable load capacity and improves the efficiency of motors and equipment.

Harmonic Mitigating Transformers are used by power quality professionals to rid commercial and industrial facilities of the power quality problems associated with harmonic currents. Harmonics are imposed on distribution systems by adjustable speed drives, electronically ballasted lighting, the power supplies of every computer, copier and fax machine. This transformer has ability to attenuate harmonic currents. This transformer can reduce the energy losses that harmonics would otherwise cause in conventional transformers. Harmonic mitigating transformers use phase shifting, electromagnetic flux and source impedance to help reduce harmonics in electrical distribution systems. It is selected to cancel positive and negative sequence harmonic currents on the transformers primary bus or within the transformers secondary windings.
