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.
Part numbers with ACT in the middle (ACT series) are accurate
to ± 0.75% from 1% to 120% of rated primary current. They
also have exceptionally low phase angle error, which is
essential for accurate power and energy measurements. ACT
series CTs comply with the linearity and accuracy
requirements of IEEE/ANSI C57.13 for tenant submetering and
billing. These CTs swing open for one-handed operation.
Part numbers with CTS in the middle (CTS series) are accurate
to ± 1% from 10% to 130% of rated current. This level of
accuracy is suited to most energy monitoring applications.
Each CT has an internal precision burden resistor across the
secondary. Each CT includes 8 ft (2.4 m), twisted-pair, 22 AWG
leads.
See specifications and dimensions on the following pages.
Monitoring Energy
These split-core CTs are recommended for use with the
OptoEMU Sensor™ 3V energy monitoring unit.
The OptoEMU Sensor 3V 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
Split-Core Current Transformer, ACT Series
historical use, eliminate guesswork, and pinpoint problem
areas to reduce energy costs.
You can also use energy data from the OptoEMU Sensor in
control systems and company databases. For more
information, see form 1936, the OptoEMU Sensor 3V Data
Sheet.
These CTs are also recommended for use with the SNAPAIPM-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 Power Monitoring
Modules Data Sheet, form 1453.
