- Page 4 For the optimal connection of Automatic PFC System, are necessary some simple operation that have to be absolutely respected. Following, are showed the steps that is necessary to follow for the installation: 1. Earth Connection of Secondary of Current Transformer (C.T.) 2.
- Page 5 Follow, please find some no-corrected positioning of C.T. Position 2: C.T. installed on the top of all loads, but on (L3-T) Phase, instead of (L1-R) Phase. Position 3: C.T. is installed on the same line of loads!! Position 4: C.T. is installed on Phases that supply Automatic PFC System.
- Page 6 6. REGULATIONS 6.1 INSTRUCTION FOR THE USE OF AUTOMATIC PFC CONTROLLER PCRL Series PCRL is an Automatic PFC Controller, based on a Microprocessor controlled circuit, able to Switch-ON and OFF the banks needed to maintain the selected Power Factor. The instrument effects an RMS value measurement that allows the optimal operation and visualization even in presence of distorted waveformes.
