AC Split-Core Current Applications

You don’t have to sacrifice accuracy to take advantage of the easy installation provided by using an AC split-core current transducer instead of a solid-core design. Any load from 200 to 800 amps can be monitored accurately using NK Technologies’ AT or ATR current transducers in the MS case. The split-core case allows the conductors to remain in place, and the base can be snapped on to a DIN rail, attached with screws to a control panel or suspended from the conductors using nylon cable ties. Some applications where the use of this type of transducers is ideal include:

Pump Monitoring:
Monitoring the current used by a pump will help to detect several problems that need immediate attention: Loss of head pressure and open discharge will cause the current to drop, and either can damage the equipment or the environment quickly. Bearing wear and impeller cavitation will be reflected in a rise in current. By mapping this increase over time, the equipment can be maintained or repaired before a catastrophic failure occurs.

Crusher/Grinder/Shredder Operation:

Crushers, shredders, and grinding processes are notoriously hard on the drive components. Inconsistent material density, foreign objects, and over loading the in feed can cause the drive motor current to spike. If these spikes occur without sufficient time to dissipate the heat generated, the motor insulation will suffer. With enough over loading a shaft might break, and the drop in current will indicate the motor is still turning but the rest of the operation is at a stand still.

Lumber Milling and Processing:

Lumber processing requires heavy duty machines, using massive hydraulic, pneumatic and electrical systems. Monitoring the current used by a log carriage will help the operator feed the cut with little burning. The saw blade can also be monitored as it will draw more current as the teeth become dulled.

A split-core CT is utilized as a part of existing conditions where the power may not be cut off. For this circumstance you can utilize these measuring curls, which can be opened so they can be put over the wire. Split-center CTs are bigger and more costly than 3CTees. It is vital to be sure there is adequate space to introduce it in the container. CATECH Split-Core Current Transformers (CTs) give straight yield voltage that is straightforwardly relative to the info current. These transformers are securely and effectively introduced over existing electrical cables without separating the lines or interfering with benefit. CATECH vitality observing parts are utilized for an assortment of utilizations including building computerization, occupant submetering, execution check, vitality administration, and new innovation evaluation. These gadgets are focused for use with the Siemens MD Series Power Meters. Split Core Current Transformers are intended for establishment into

Current transformers are by and large situated in the fundamental breaker board or in branch dispersion boards where space is dependably at a premium. Since current transformers don't need to be introduced 90° to the conduit run (the channels/wires can experience the present transformer at any edge), they are by and large held set up with plastic tie wraps or other comparable gadgets. Current transformers with mounting feet are additionally accessible if appearance is critical or if there is sufficient room in the board to suit this sort of mounting. In the event that a CT test switch is utilized, the switch must have a "make-before-break" contact example to guarantee that the present transformers are not open-circuited amid change. Regularly present transformers ought NOT be introduced on "HOT" administrations. The power ought to be separated amid establishment. In any case, generally this isn't conceivable because of basic loads that can't be cl
