LZCK-55 GFUVE 100A/5A IP67 Outdoor installation Split Core Clamp On
Current Transformer
Clamp-On Current Transformer's are designed for fast and easy
installation. Clamp-On CT uses Permalloy Magnetic Core or Silicon
Amorphous Core, with characteristics of small size. high precision,
good stability and strong anti-interference ability.
Clamp on current transformers are used for long term energy studies
which includes electric power quality monitoring device. It is
ideal for power and energy measurement.
Clamp on current transformer is a high-precision AC current
converter, and can meet a variety of measuring instruments, It can
be used along with many kinds of instruments and devices, such as
energy meter spot calibrator, multifunctional meter, oscilloscope,
digital multimeter, dual clamp Ground resistance tester, dual clamp
phase volt ammeter. Parameters will be measured and compared
without power supply cut-off on account of the split core.
Clamp-On Current Transformer is the one-handed operating solution
for temporary energy audits or long-term energy studies. The GFUVE
P50 1000A Clamp on ct is specifically designed to offer broad
utility in a compact shape. These CTs deliver high-accuracy,
high-sensitivity, versatility, and low phase shift.
Applications
IP67 Spit core clamp on current transformers are the
current-sensing units of the power system. Split core current
transformers are used at generating stations, electrical
substations, and in industrial and commercial electric power
distribution.
LZCK-55 waterproof outdoor split core current transformers are
applicable for AC power system 35kV and measurement of current of
power supply equipment below 10KV also can be used for
microcomputer protection. This type of current transformer employs
imported silicon steel which with high permeability as magnetic
material, has the characteristics of Small magnetic circuit loss
and can be split, its semicircular core and secondary windings
employ high quality epoxy resin vacuum, casting in plastic-case(ABS
or PC) which is flame retardance anti-moisture, stable performance,
no maintenance.
Features
New magnetic material is taken to be the core of the current
transformer, which has high magnetic permeability, low saturation
magnetization and good stability. Therefore, the measuring accuracy
is higher and the instrument security factor is lower. Since the
high quality silicon processed by advanced technology is taken to
be the core of the protection windings, which assured the accuracy
limit factor is higher.
The semicircular ring core and secondary windings are vacuum poured
by high quality epoxide resin in the fire retardant plastic casing,
which has the characteristic of moisture proof, stable performance
and dispensing with maintenance.Small size, light weight, small
footprint, fixed in the ring network switchgear cable.The cable can
cross the current transformer through its internal poles quickly
and uniformly.
The Cast Resin Straight-Through Current Transformer can be divided
several kinds according to the various current ratio, accuracy and
rated loads. The specific parameters are showed in the
corresponding to each model parameter tables.
