500KV Ultra High Voltage AC Harmonic Filter Resistors with CE Approved

The harmonic filter resistors are custom designed for different applications by considering the voltage, current, inductance, size, loss characteristics that are required to provide the most efficient design at the most economical prices.Using stainless steel resistor elements, excellent high voltage strength, low inductance resistor elements for easy tuning and corrosion and heat resistant electrostatic paint for indoor and outdoor applications.

Filter resistors are also an essential component in HVDC converter stations, where they act as part of the harmonic filters used to dissipate unwanted harmonics produced by the solid-state converters.

Features:

1.Small land space:The tower type connection among resistor cases significantly reduces the land space for filtering field;

2.Highly reliable insulation: Porcelain insulators are used between the case and base,between the cases as well as between resistor line and case and between different resistor lines for insulation and support.

Application:

Harmonic filters are widely used in industrial applications where there are concerns about harmonic distortion caused by the increasing number of nonlinear power electronic and solid state devices. Harmonic distortion causes stress and resultant problems for a plant's power distribution system, as well as all of the equipment that is serviced by that system. In addition, harmonics increase current, causing increased operating temperatures for many pieces of equipment, resulting in greatly reduced equipment life. The primary objective of a harmonic filter is to reduce the amplitude of one or more fixed frequency currents or voltages.
