  Frequently Asked Questions:

To balance the imbalance currents and correct reactive power, shunt active filters are employed to correct current harmonics of nonlinear loads. To counteract current harmonics or reactive load, a shunt active filter detects the load current and injects a current into the system.

What is the purpose of a harmonic filter?

Harmonic filters reduce distortion by diverting harmonic currents in low-impedance paths. Harmonic filters are capacitive at the fundamental frequency, so they are also used to produce the reactive power required by converters and for power factor correction.

Why is the harmonic series important?

Brass instruments, in particular, benefit greatly from the harmonic series. A pianist or xylophonist can only produce one note per key. When a string player wants a certain note from a string, they grip the string tightly in that location. In essence, this creates a vibrating string with a new length and fundamental.

Why is it called harmonic series?

The harmonic sequence is so named because it is exactly the sequence of points on a taut string that deliver musical "harmonics" when the string is touched there as it is plucked.

Who proved harmonic sequence?

The study of harmonic sequences dates to at least the 6th century bce, when the Greek philosopher and mathematician Pyt 

Superior Harmonic Suppression

The Series Shunt Harmonic Filter Reactors are specifically designed to mitigate unwanted harmonics in low voltage electrical systems. They target major harmonic orders, such as 3rd, 5th, 7th, 11th, 13th, and above, significantly improving system performance by reducing distortion and increasing equipment longevity.


Robust and Reliable Construction

Built using high-quality copper or aluminum windings and silicon steel laminated cores, these reactors ensure durability and efficiency. Their robust design, powder-coated surface, and IP20 protection make them suitable for Indian industrial environments, supporting prolonged operation under high thermal and humidity conditions.


Flexible Installation and Operation

With panel or floor mounting flexibility and options for star or delta connection, the reactors can be seamlessly integrated into existing systems. Their noise level is maintained below 55 dB, and thermal class F/B insulation provides overheating protection, ensuring stable performance even at temperatures between -25C to +45C.
