Feature: 1. The open close high accuracy current transformer is suitable for the detection of AC leakage current, high order harmonic current, phase, electric energy, power factor, etc. 2. Using new CT technology, no need to disconnect the line under test, non contact measurement, accurate measurement, safe and fast. 3. The iron core is made ofpermalloy and double layer shielding technology is adopted, so the influence of the external magnetic field is very small. 4. This product is easy to operate and easy to carry, ensuring high stability and reliability for year round uninterrupted measurement. 5. It can be connected to phase detection analyzers, industrial control devices, data loggers, oscilloscopes, harmonic analyzers, power quality analyzers, high accuracy digital multimeters, etc. Specification: Item Type: Leakage Current Sensor Model: ETCR025K Material: ABS+permalloy Application: Electric power, communications, meteorology, railways, oil fields, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fieldsRange and Accuracy:RangeResolutionAccuracy ClassPhase ErrorTransformation Ratio0.00mA~30A AC0.01mA AC0.5≤2° 800:1Other Parameter: Function AC leakage current, high order harmonic current, phase, electric energy, power, power factor, etc. detection Detection Method Open and close structure, no need to cut off the line under test without power failure, especially suitable for online installation CT Size ΦApprox. 25mm / 1in Measuring Range 0.00mA~30A AC Transformation Ratio 800:1 (can be customized according to needs) Phase Error ≤2° Secondary Load ≤10Ω Shielding Double layer shielding, suitable for complex interference environment Output Method Inductive current output Output Interface Wiring terminal (S1, S2 coil tap end, GND shielding end) Frequency 10Hz~100KHz Security Level CATⅢ600V External Size Approx. 78 x 82 x 31 mm / 3.1 x 3.2 x 1.2 in Quality Approx. 120g / 4.2oz Operating Temperature -15°C~50°C Dielectric Strength AC 3700V/rms (between iron core and shell) .
