?????????????????????????????????????????????HY-ZCT zero sequence current transformer has unique features that make it well suited for precise applications relevant to fault detection, safety and system checking.In distinction, the overall stage present-day won't be zero beneath abnormal instances. A zero sequence present will then flow during the

While in abnormal conditions, the sum of phase current will not be zero. Then as a result of unbalancing of stage present-day, a zero sequence latest will move during the secondary circuit of CBCT.Relay defense coordination: HY-ZCT plays an important function in relay defense coordination. By accurately measuring the residual latest below fault ail
