3 Automatic capacitor banks CIRCUTOR's range of capacitor banks for contactor switching operations cover power levels 7.5 kvar to 1120 kvar (in the case of greater power levels, please ask). Initial data: Data that must be taken into account when selecting a capacitor bank: Total power factor consumption of the installation and cos φ objective. Voltage: the voltage of the unit must always be equal to or higher than the network voltage. Harmonic distortion levels Simultaneity of loads. Regulation of the capacitor bank: we recommend an approximate power of 10% of the total power of the unit in the first step. Technical instruction ITC-BT-43 of the REBT, section 2.7 (Power factor correction) must be taken into account when selecting a capacitor bank: The installations that supply energy to receivers with a power factor under 1 can be compensated. However, the energy absorbed by the network can not be capacitive. The Power factor correction process can be carried out as follows: For each receiver or group of receivers operating at the same time and which are connected with a single switch. In this case the switch must cut off the power supply of the receiver or group of receivers and capacitor at the same time. For the whole installation. In this case, the compensation installation must be designed to make sure that the variation of the power factor does not automatically exceed ± 10% of the mean values obtained during a long period of operation. As a consequence, the installation can be compensated automatically at the header or individually. Automatic compensation at the header When selecting an automatic capacitor bank, it is important to distinguish between the number of electrical steps and the number of physical steps. The number of physical steps is described by the number of contactor + capacitor groups. In turn, electrical steps are defined by the different electrical R.3 combinations of the unit. The number of electrical steps is the result of dividing the total power of the unit by the power of the lowest step. Here is an example. Example: 440 kvar Capacitor bank Composition: (40 + 5x80) This capacitor bank has 6 physical steps: One 40 kvar step and five 80 kvar steps, and 11 electrical steps: 11 x 40 kvar. From the point of view of efficiency, it is very important that the capacitor bank has enough electrical steps that can adapt to the demands of cos φ. A good balance between the physical and electrical regulation will allow us to fine tune the system at the lowest price. R3-3
