Serie QSRB35

Capacitor bank without regulation known as fixed compensation

Used when reactive power to compensate is constant and when the load is working 24h / 24h.

Used when reactive power is to compensate for low power. Also standardized by the coefficient QC (Compensation to install in KVAR) / SN (Transformer power in KVA) is generally <15%. This threshold of 15% is indicative and we recommend it to avoid to overcompensate the charge power vacuum.

Used to directly compensate the asynchronous motor, load losses of the line head transformer.
