PFC Thyristor Unit Upgrades

After carrying out power quality review at a large electrical component manufacture, the rapid fluctuation in load means that standard Power Factor Correction equipment cannot switch fast enough to correct the PF. As such thyristor switching contactor modules were required along side de-tuning reactor to help reduce harmonics.

 

Theses newly designed FSi Fast Switching units are split into 6 stages of 50kVAr each with its own 189hZ de-tuning reactor all controlled via an 8 stage Lovato DCRG8F digital control relay specifically designed for thyristor switching.

 

As most of these new Thyristor units were replacing existing PFC equipment, we were able to reuse the existing power cables and c.t circuits. This work was carried out by 3 engineers over 3 days during normal working hours
