6 FAQs about [Managua Reactors and Capacitors]

Why are detuned reactors used in series with capacitors?

Hence, the use of detuned reactors in series with capacitors offers higher impedance for harmonics, thus eliminating the risk of overload in capacitors. The inductance value of detuned reactors is selected such that the resonance frequency is less than 90% of the dominant harmonic in the spectrum.

Why do block reactors need capacitor banks?

One of the unwanted effects is the overheating of capacitor banks that are needed to maintain the power factor within the parameters required by the power authority, with a resulting, significant reduction in the average working life. The ideal solution is to insert block reactors in series with capacitor banks.

How to calculate capacitance of 3 phase capacitor with detuned reactor?

It will be calculated from the following equation: For 3 phase capacitor with detuned reactor , the capacitance equal 3 x 332 μF at 400 V /50 Hz with blocking factor p = 7%. Calculate the capacitor KVAR. We should choose a capacitor with nominal voltage Un higher than Uc.

What is a kvar rated capacitor?

Capacitors are rated in KVAR. Common sizes are 1, 2, 3, 4, 5, 6, 7, 8, 10/12/15/20 and 25 KVAR at 415 or 440V alternating current, 3 phase, 50 Hz. Usually more than one capacitor is required to give the desired degree of power factor correction. Groups of capacitors are factory assembled in various configurations.

Can a low-voltage reactor be fitted with a TEM-perature control device?

All low-voltage reactors can be fitted with a tem-perature control device in the center coil (available for all coils, if requested). Medium-voltage reactors are available with tem-perature monitoring in the core only. The sensors can be microswitches (normally closed or normally open), thermistors or PTC sensors.

Can a copper bar terminal be installed on one side of a reactor?

Terminals can be fitted on one or both sides of the reactor. If de-sired, support insulators at top of the reactor can be provided for fixing the copper bar terminals. standard. With reactors of this type, the core is con-nected to the serial connection of the two coils.
