electronic measuring instruments

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. 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.
