200A Outdoor Split Type Current Transformer For Cable fault monitoring, class 0.5
Theory
Split core current transformers are high accuracy class electrical devices used to isolate or transform voltage or current levels. The most common usage of current transformers is to operate instruments or metering from high voltage or high current circuits, safely isolating secondary control circuitry from the high voltages or currents. The primary winding of the transformer is connected to the high voltage or high current circuit, and the meter or relay is connected to the secondary circuit. Installation With electricity, suite for power monitor, energy loss etc.
Split core current transformers may also be used as an isolation instrument transformer so that secondary quantities may be used in phase shifting without affecting other primary connected devices.
Applications
Spit core 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.

2. Power quality monitoring
3. energy meter measurement
4. Switch cabinet
5. Cable fault monitoring
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.
