Boost Transformer Internally Bypassed 

When the AVC is not online the boost transformer primary must be short circuited



Online means the AVC is running providing voltage regulation and sag correction



When internally bypassed the boost transformer “from an electrical perspective” appears as a reactor (inductor) in series with the load



Typical Internal bypass Impedance 150% for 30 seconds

PCS100 UPS-I, Industrial UPS Short term outage protection

© ABB Group April 13, 2015 | Slide 33

PCS100 UPS-I, Industrial UPS There is a solution

© ABB Group April 13, 2015 | Slide 34



The PCS100 UPS-I is the ideal solution where very deep sags or short term power outages are a problem



The PCS100 UPS-I uses energy storage coupled through an inverter to allow the downstream load to ride through very deep sags and short term outages



The PCS100 UPS-I is an offline system. It is inactive unless the voltage falls by 10% - 13%. This enables it to be very efficient, up to 99%
