What is TPS class current transformer?

TPS Class CT is used for transient performance (TP). TPS class Current Transformer has Low Leakage Flux and there is no limit for remanent flux) further there are also TPX,TPY and TPZ class CTs

1. TPX- No Limit for remanent flux due to nil air gap in the core

2. TPY - remanent flux does not exceeded 10 % due to less air gap in the core

3. TPZ- Having practically null remanent flux because there is large air gap is provide in the Core
