Product DescriptionCurrent TransformerWhat's this product? The Current Transformer (CT) is an electrical device that operates based on the principle of electromagnetic induction. It is primarily used to proportionally convert high currents in three-phase circuits to smaller currents, thereby providing suitable current signals for equipment such as measuring instruments and protective devices. Widely applied in power systems for measurement, metering, protection, and monitoring, it effectively ensures the safe and stable operation of power systems.Functions.1.1 Current measurement ≡ Universal for high/low voltage systems Directly measuring high currents in either high-voltage or low-voltage circuits is hazardous. Three-phase current transformer (CT) can proportionally step down high voltages or large currents to low-voltage or currents, enabling safe and accurate measurements. For example, in a 10 kV high-voltage distribution system, currents may reach hundreds or even thousands of amperes. By using a current transformer to convert these to a secondary current of 5A or 1A, standard ammeters can easily measure and display the values. ≡ Multi-Device compatibility The current transformer (CT) is compatible with various measurement instruments such as ammeter, power meter, and energy meter, providing them with appropriate current signals to accurately measure parameters like current, power, and energy in three-phase circuits. For example, in a factory's power distribution room, connecting the current transformer to an energy meter enables precise measurement of electricity consumption, offering a reliable basis for billing and cost settlement.1.2 Protective relaying ≡ Fault current sensing When a short circuit or overload occurs in a power system, the current surges abruptly. The three-phase current transformer (CT) promptly and accurately transmits the fault current signal to protective relays, enabling them to act swiftly and trip the faulted circuit. This critical function safeguards the power system by isolating faults and ensuring its safe and stable operationFeatures1, High precision measurementUtilizing high-quality iron core materials and advanced manufacturing processes, the current transformer ensures high accuracy in current conversion with minimal measurement errors. This provides reliable data support for precise metering and monitoring in power systems2, Wide measurement rangeTo accommodate various application needs, the current transformer offers multiple range options. It can handle three-phase current measurements ranging from tens to thousands of amperes, meeting the operational requirements of diverse and complex power systems.3, Good linearityWithin the rated current range, the output current maintains an excellent linear relationship with the input current. This ensures the accuracy and reliability of measurement results, effectively avoiding deviations caused by nonlinear errors4, High insulation performanceEquipped with excellent insulation materials and structures, the device can withstand elevated voltages, effectively preventing safety hazards such as electrical leakage and short circuits. This ensures the safety of both operating personnel and equipment.Technical Specification(Custom configurations available upon request.)Model No.STW50Insulation resistanceDC500V/1000MΩ /minMeasurement range10In130InHousingABS,Flame retardant grade 94-V0Operating frequency50400HzBobbinPBTRated output10mA5ACoreNickel Steel or NanocrystallineRatio error±:0.1 Working temperature-25° +75°Phase error±:10mAmbient humidity85Dielectric strength2.5KV/1mA/1minWiring ConfigurationTerminal Type/Shielded Stranded Wire 1.5mCompany ProfileApplicationCertificationsPackaging & ShippingFAQQ: What is the lead time for orders?A: Our standard models are dispatched within a swift 15–30 days, while our customized units, tailored to your specific needs, require a careful crafting process of 30–45 days to ensure perfection.
