BATLVF automatic LV capacitor banks with 7 % detuning filters (contactors), 25–1200 kvar
Country: Spain · Model: BATLVF
BATLVF automatic capacitor banks compensate 25–1200 kvar of reactive power in low-voltage networks with a high harmonic level, because each of their steps has a p = 7 % protective filter. They are installed at plants with frequency converters, rectifiers and other non-linear loads, in the petrochemical and metallurgical industries, at water treatment works and at large commercial sites.

Description
In each step the FMLF or POLB HD 7 % capacitors are connected in series with INA/INR reactors, and this detuned circuit is tuned to 189 Hz. This frequency lies below the fifth harmonic, so harmonic currents do not overload the capacitors and there is no resonance with the network inductance. The steps are controlled by the MASTER control Var controller with switching programs 1.1.1–1.9.9, switched by standard contactors, and each step is protected against short-circuit currents by NH00 fuses. The controller receives the current signal from an external current transformer …/5 A, which is not included in the supply. To order, the cabinet is supplemented with an input load switch or circuit breaker and earth leakage protection. The floor-standing metal IP21 cabinet is painted RAL 7035 and is designed for indoor operation at a temperature of −25…+45 °C. The banks comply with IEC 61921:2017 and operate at oil refineries in Spain, and a BATLVF1000 stands in the GALP project in Portugal.
How to choose
The size is chosen by the required power at the rated voltage of 440 V, 50–60 Hz. The BATLVF120 covers 25–120 kvar, the BATLVF400 gives 150–400 kvar in a 900 × 650 × 1900 mm cabinet, the BATLVF600 gives 375–600 kvar, the BATLVF800 gives 575–800 kvar, and the BATLVF1200 for 975–1200 kvar consists of two LVF600 cabinets. With weak harmonics, BATLV banks without filters for 150–1600 kvar are enough, for loads that change within fractions of a second the thyristor BATLVFS is taken, and for phase balancing the SVG-L generator for 30–400 kVA is suitable.

FAQ
How is the power of a BATLVF converted from 440 V to 400 V?
The reactive power of a capacitor is proportional to the square of the voltage, so at 400 V it is lower. For example, the BATLVF4044250 gives 250 kvar at 440 V and 207 kvar at 400 V.
What steps does the BATLVF4044250 bank have?
Steps of 50 + 2 × 100 kvar, which gives 5 steps of 50 kvar. The weight of the bank is 390 kg, which must be taken into account during transport and floor installation.
Is the current transformer included with the BATLVF?
No, the current transformer …/5 A is ordered separately and installed on the incomer so that the controller sees the total load current. The primary current is selected according to the incomer current.
Why does a capacitor bank need a 7 % filter?
The reactor and capacitor form a circuit tuned to 189 Hz. Below this frequency the step works as a compensator, and at harmonic frequencies as an inductance, so resonance with the network is ruled out.
