Compact Zero Sequence Current Transformer Ring Net Cabinet 5P10 Ratio 100A / 1A

LZCG530-10 Zero Phase Current Transformer, Ring net cabinet 5P10 Ratio 100A / 1A Zero Sequence Current Transformer

100A Zero Phase Current Transformer The 200A zero phase current transformer can endure input current ranging from 50A to 100A. If the monitored circuit malfunctions, it can output zero phase current which is 500 times smaller than the input current with the suggested 500 turns ratio so that the power supply is cut off to protect the electric equipment.

The unbalanced current flows in the circuit during the earth fault is known as the zero sequence current or the DC component of the fault current.The zero phase sequence means the magnitude of three phases has zero phase displacement.The three vector lines represent the zero sequence current and it is detected by adding the vector of three phases current.

Zero phase current transformer which detects the difference between the currents flowing in a number of conductors. The current flowing to a load must equal the current flowing back from the load. If this is not the case, a potentially dangerous residual current will be flowing somewhere in the installation.

LZCG530-10 Straight-Through zero sequence Current Transformer is suitable for current measurement and microcomputer protection of electrical equipment in 10KV and 35KV AC power system. It is widely used in not only compact fully insulated ring network switchgears such as ABB-Safe Ring/Safe Plus, Unstitch, Schneider RM6, SM6, Siemens 8DJ10/8DH10, Simosec, FBX, Fluokit, Omar Garbo GA, GAE; SEL TPS(Q); VEI Unifluorc; Eaton SVS/12 ring network, but also cable distribution boxes because of its small size, light weight, operable and convenient installation. It is very convenient that the transformer can be directly installed at the inlet and outlet cables.

Definition: The unbalanced current flows in the circuit during the earth fault is known as the zero sequence current or the DC component of the fault current.The zero phase sequence means the magnitude of three phases has zero phase displacement.The three vector lines represent the zero sequence current and it is detected by adding the vector of three phases current.
Zero sequence current transformers, also known as core balance current transformers (CBCT), detect the presence of zero sequence currents during short circuit fault conditions such as the occurrence of a single line to ground fault that causes unbalanced currents in three-phase systems.
Zero sequence filtering is a concept used to eliminate zero sequence current component from the secondary current of Current Transformer used in Differential Protection of Transformer. This concept is useful in Transformer having earthed Star winding.

Zero-phase-sequence current transformer A current transformer has a primary winding, a core and asecondary winding, although some transformers, including current transformers, use an air core.
