Split-Core Current

Transformers

Description

These split-core current transformers (CTs) from Continental

Control Systems offer an easy, safe, and inexpensive method

for monitoring electrical energy usage.

Ideal for retrofit applications, the split core makes it possible to

attach the CT without disturbing existing wiring. Just open the

CT, slip it over the wire, and snap the CT closed. Once

assembled, the CTs have no exposed metal parts.

The 0.333 VAC output of these CTs is low, making them much

more safe to install and use than CTs with current secondaries.

These CTs are also less expensive than their current cousins.

While less accurate than CTs with a current secondary and

therefore not designed for metering applications where high

accuracy is necessary for billing purposes, these CTs are

accurate to ± 1% from 10% to 130% of rated current. This level

of accuracy is well suited to energy monitoring applications.

Each CT has an internal precision burden resistor across the

secondary and is core interleaved at joints for accuracy. Phase

angle is measured at 50% of rated current. Each CT has an

epoxy-encapsulated housing and includes 8 ft (2.4 m),

twisted-pair, 22 AWG leads.

See specifications and dimensions on the following page.

Monitoring Energy

These split-core CTs are recommended for use with the

OptoEMU Sensor™ energy monitoring unit.

The OptoEMU Sensor is a simple appliance that monitors the

electrical energy used in your facility and then uses your

existing wired or wireless Ethernet network to deliver that data

to online software applications. You can see real-time and

historical use, eliminate guesswork, and pinpoint problem

areas to reduce energy costs.

These CTs are also recommended for use with the SNAP-

AIPM-3V analog input module, which monitors power from a

3-phase load. The module measures voltage and current from

each phase; it calculates watts and volt-amps for each phase

plus true power sums for all phases.

Part of the SNAP PAC System, the SNAP-AIPM-3V mounts on a

rack with other analog, digital, and serial modules and an I/O

processor. For more information, see the
