CTA Conditioner and 5A output
module |
The CTA flexible current
transformers are
the world's first flexible 'clip-on' current probe with
a 5A output, allowing compatibility to existing 5A metering circuits. Unlike
conventional CTs, there are no open circuit hazards - ideal for
retrospective metering projects and installations in confined spaces
where installation of conventional iron core CTs is not possible. The
CTA flexible current sensor also simplifies
installation and eliminates the need for expensive LV/HV plant shutdown.
In addition,
these modules are used to convert any voltage output current
measuring device to a 1A or 5A secondary.
The CTA flexible
current transformers
convert ac current to an isolated 0-5A current with
available ranges from 100A to 10,000A. Because the current sensors are
flexible split
core, installation is possible without shutting down the LV electrical supply, avoiding expensive down-time costs. Typical
applications are retrospective energy monitoring in
factories, offices buildings, process control data logging systems, where power, energy and current
monitoring is important. Typical applications
are factories, offices buildings, ac/dc VFD drives,
welding, power conversion and power
distribution. For all CTA current sensor models, a NIST/NPL (UKAS)
traceable calibration certificate and certificate of
conformance is supplied. All CTA sensors use UL94V0 or CSA
approved materials.
The CTA flexible current sensors are suited to
permanent or semi permanent installation. The coil sensor is
durable, lightweight, flexible and will easily
clip-around a power cable. The 5A output from the CTA
current sensor
connects direct to installed metering, rotary metering or current transducers.
