150 5 Current Transformer Wiring Diagram

Conduit might be a better.

150 5 current transformer wiring diagram. With 150 amps through the 300 amp rated primary the secondary current will be 2 5 amps 150. Is a type of instrument transformer that is designed to produce an alternating current in its secondary winding which is proportional to the current being measured in its primary current transformers reduce high voltage currents to a much lower value and provide a convenient way of safely monitoring the actual electrical current flowing in an ac. Vv the ip 5 a ratio current transformer delivers at the secondary a current is of 0 to 5 a that is proportional to the current measured at the primary ip. Application diagram of a ct.

For example a ct with a ratio of 300 5 is rated for 300 primary amps at full load and will produce 5 amps of secondary current when 300 amps flow through the primary. 150 200 300 5a s 2 150 5a s 3 200 5a s 4 300 5a. A wiring diagram is a kind of schematic which utilizes abstract pictorial icons to show all the affiliations of parts in a system. Current transformer wiring diagram what s wiring diagram.

Refer to page 42 figure 4a construction and insulation please refer to general product information item 1 3. More stock available week commencing 8 17 20 products not normally stocked that show available inventory are in stock up to the quantity displayed. This allows them to be used in combination with measurement equipment. Conduit but if you are running any distance and have bends a 3 4 in.

Refer to the current transformer wire extension page for more information. The primary current changes the secondary current will vary accordingly. Transformer wiring diagram for single ratio current transformer. The output of the transformer decreases proportionally with the ratio.

Icons that stand for the parts in the circuit as well as lines that stand for the links. Current transformer white paper the basics of current transformers ratio the ct ratio is the ratio of primary current input to secondary current output at full load. Jkw 150 current transformer 25 000 v to 34 500 v bil 150 kv to 200 kv outdoor current dry type jkw 150 jkw 200 25 a to 3 000 a 50 60 hz. Additional quantities will ship with lead time displayed.

The diameter of ct twisted pair lead wires is about 0 213 in. Current transformer 150 5 50 hz 400 hz panel omega 30b 5drl series check stock lead times. Three twisted pair will fit in a 1 2 in. When the rated primary amps is ex ceeded which is usually the case when a fault occurs on the system the amount of secondary current will increase.

Connections are correct as per wiring diagram otherwise problems will result with the register displays for health safety reasons it should be noted that if a current transformer is operated with the secondary s1 and s2 open circuited dangerous voltages may be generated at the secondary terminals or leads. Please find some transformer wiring diagrams below. This is about the diameter of a 8 awg thwn or thhn insulated conductor. 300 2 5.
