Detuned Type Capacitor Bank

Safety precautions m warning.

Detuned type capacitor bank.

Filter design can be made into more complex configurations. This filter will do little for removing any harmonic distortion present on the system but will allow the installation of a large capacitor bank without any adverse system interactions. If harmonic filters are being considered only for the purpose of power factor correction then a de tuned filter bank is the best choice. Typically a suitable combination of small e g.

Pow er variations are relatively slow in seconds so that the switching operations are carried. A shunt capacitor bank or simply capacitor bank is a set of capacitor units arranged in parallel series association within a steel enclosure. Detuned anti resonant automatic harmonic filter. This lc circuit is called a filter a tuned capacitor or a detuned capacitor.

Capacitor banks with detuned filters fr 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. In addition to providing resonant free power factor correction the. Eaton s unipak detuned filters will also avoid resonance if applied correctly in addition to providing reactive power vars for displacement power factor correction. If 25 n ll 50 our suggestion is a heavy duty pfc capacitor bank with suitable harmonic detuned reactors.

If the traditional floor model detuned filter capacitor bank is too large or cannot be installed on the floor for other reasons. The steps are selected depending on the fluctuation of compensation needs in the system. Practical approach in design and installation of detuned capacitor banks photo source. But from a purely technical stand point this is a simple rlc band pass filter the resistive portions of the inductor and the capacitor will determine the quality factor of the filter.

If n ll 15 we normally recommend a standard pfc capacitor bank. Pdf 302k question request a quote. Capacitor banks may be star or delta connected. Detuned automatic capacitor bank ft100.

The controller turns the compensation steps on off as needed. Capacitor banks are intended for correction of displacement power factor at and upstream of the connection point of the capacitor bank. Detuned filter reactors detuned filter reactors are used in series with capacitor banks in power factor correction units. Usually fuses are used to protect capacitor units and they may be located inside the capacitor unit on each element or outside the unit.

The ft100 series anti resonant harmonic filter offers a secure solution for power factor correction on networks with harmonic content. 25 kvar and large e g. If 15 n ll 25 you may want to consider a heavy duty pfc capacitor bank. 50 kvar compensation steps are needed.

If n ll 50 we recommend installing an active harmonic filter. A detuned filter capacitor bank is comprised of suitable compensation steps. 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.
