Detuned Reactor Capacitor Bank

Detuned filter reactors detuned filter reactors are used in series with capacitor banks in power factor correction units.

Detuned reactor capacitor bank.

Permissible distortion limits of the local utility of ieee 519 are exceeded and filters are required to reduced them. Based on vthd and ithd present at various sites reactors are futher. Installation of a plain capacitor bank. The series reactor of rating 0 2 of the capacitor kvar is used to limit the current.

A comination of pfc capacitors with detuned harmonic filter reactors will result in limiting harmonics. The fr series capacitor banks with detuned filters have been designed for power com pensation purposes in networks with fluctuat ing load levels a high content of harmonics and where there is a risk of resonance. By using these types of detuned reactors it is possible to avoid fol lowing negative effects on system overcurrent during switching on the capacitor banks overload of capacitor banks because of the harmonic resonance. In applications where harmonic current distortion is high due to the use of nonlinear loads series reactors are used to detune the capacitor bank parallel resonant point.

Harmonic filter detuned reactors do not destroy harmonic components in the system. Prolongs life of pfc capacitors by. It is a well known misinformation to say that it destroys harmonics in the system. Capacitor is widely used in industry to improve power factor.

Also this series lc. Among these catagories 7 reactors are most famous and constitute about 80 of the orders. To use a detuned reactor you need to make a correct assessment of the risks of capacitor bank resonance in your installation we recommend the following procedure. They are also used in series to tune the series resonant point of the capacitor to act as a harmonic filter.

It only prevents the harmonic current from increasing in amplitude. The reactor consumes power because of the ohmic resistance of the reactor and produces hea. Take measurements over a significant period minimum one week of the voltages currents power factor level of harmonics individual and global thd u thd i. Detuned reactors or harmonic filter reactors are used in power factor correction panels in series with capacitors to avoid resonance due to presence of harmonic currents of various frequencies.

Benifits of using detuned reactors 1. But capacitors need a series reactor to limit the starting inrush current. Harmonic filter detuned reactors can be manufactured as single phase or three phase choosing the tuning frequency according to the dominant harmonic current order in the system according to the bus bar voltage and capacitor impedance power.
