The most common usage of currenttransformers 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.ApplicationLZCK waterproof Outdoors Split Core Current Transformer applicable for AC power system 35kV and measurement of current of power supply equipment below 10KV, and microcomputer protection. This type of current transformer employs imported silican steel which with high permeability as magnetic material, have the characteristics of Small magnetic circuit loss and can be cut, its semicircular core and secondary windings employ high quality epoxy resin vacuum, casting in plastic-case which is flame retardance anti-moisture, stable performance, no maintenance.FeaturesNew 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.Working conditions:Ambient temperature: -35~+55.Environment: Outdoors or indoorsThe Height of above sea level: 0~ 3000m.Atmosphere conditions: No highly polluted, errosion, erosiveness, radioactivity gases.(continuous working under the rated current is allowed)(P2 represents for primary polar end, S1, S2 represent for secondary polar endP2 and S2 are subtractive polarity.Technical parameters: :Rated frequency: : 50Hz or 60HzRated secondary current: 5A or 1ASecondary winding power frequency withstand voltage: 3kV, 1minSafety Factor Rating (FS) < 5Standard of Application: GB1208-2006; IEC 60044-1; NTC 2205Accuracy Class: 0.5 or 1;Flame retardant ABS plastic shell or PC inside the filling, jaw waterproof apron.Item NameRange of primary rated currentRange of Rated loadAperture(mm)Description (mm)(Weight)(kg)LZCK-55100-1500A≤10VAΦ55180×138×522LMCK185-10300-3000A≤10VAΦ185350×283×554.5PARAMETERSTechnical parametersStandardsIEC60044-1; IEC 61869-2; NTC 2205; GB1208-2006; ANSI C57.13Accuracy Class0.5S, 0.5%, 1%, 3%Range of primary rated current100-1500ARange of Rated load≤10VARated frequency50/60HzRated secondary current5A or 1ARated short-time thermal current40kA, 1SRated continuous thermal current150%I1nSecondary winding power frequency withstand voltage3kV, 1minSafety Factor Rating(FS) <10Output signal1A, 5A, 333mV, 1V or 5V(customized)Cable length2.5m, 5m, 10m(customized)Flame retardant ABS plastic shell inside, jaw waterproof apron.Mechanical parametersAperture (mm)Φ55Dimensions (W×D×H) (mm)180×138×52Weight (kg)2Working conditionsOperating temperature-35°C to +65°C, not exceeding +40°CStorage temperature-40°C to +70°CIngress ProtectionIP65Environmentoutdoors or indoorsThe Height of above sea level0- 3000mConditionsNo existence of severely begrimed, erosive and radioactive gas in the air.
