Static Transfer Switch (STS), Static Current Limiter (SCL), Static Circuit Breaker Fast switching for fault isolation and rapid load transfer. Static Transfer Switch (STS), Static Current Limiter (SCL),

are a new generation of power electronic controllers designed for medium to low voltage levels (typically 1 KV through 32 KV) to ensure high-quality power delivery. Unlike Flexible AC Transmission Systems (FACTS) which focus on high-voltage transmission, CPDs are specifically applied at the distribution level to protect sensitive consumer equipment.

DSTATCOM, Dynamic Voltage Restorer (DVR), Unified Power Quality Conditioner (UPQC)

The UPQC is considered the most powerful CPD as it combines both converters via a common DC link.
