Description

1. The static switching modules of the JK3PSZT3 series are the basic building block for the construction of static capacitor banks for power factor correction purposes. These capacitor banks use thyristors instead of the classic contactors for the connection of each large group of capacitors and they are ideal in installations where the leakage current suffers quick and large fluctuations (load changes in intervals that can range from split seconds to 8 or 10 seconds).

2. The static switching units of the JK3PSZT3 Series have been designed to connect and disconnect capacitors in milliseconds. They can be used to build capacitors with various steps, or for the individual compensation of a load that must be compensated instantly due to connection / disconnection deficiencies, for example, in welding units, cranes, lifts, etc.

3. Automatic capacitor banks with static system - JK3PSZT3 Series
The JK3PSZT3 Series capacitor banks with static system have been designed for Power factor correction purposes in networks with fluctuating loads. The variations in power are relatively fast (in milliseconds) so that the switching operations are carried out by thyristors, which are connected to a voltage control board, so that the connection and disconnection of the capacitor is carried out with a zero voltage difference. Transients are prevented between the connection and disconnection of steps, obtaining the immediate response to the load fluctuations.

4. Functions and advantages of capacitor banks with a static system. The functions or advantages of this compensation system are as follows:Immediate response to the compensation request. The response time of the Power factor correction can be of a single network frequency cycle, thus achieving an almost instantaneous compensation. Elimination of start-up transients produced by the capacitor's connection. The connection takes place when the voltage network matches that of the capacitor when it is partially or totally loaded, as seen Fig.1.
