Low-Voltage Current Transformers (~0.72 kV)
Widely used internationally in revenue and switchboard applications by engineering, construction, and power companies, CIC Current Transformers are the result of over 40 years of manufacturing expertise, combined with technology transferred from Messwandler-Bau (MWB) of Germany.
The primary insulation material for CIC's current transformers is the Araldite® epoxy resin, known for its reliability. The outdoor models make use of cycloaliphatic epoxy resin, similarly to ensure high-quality insulation.
CIC's current transformers, including OEM/ODM products, are type-tested and routine-tested by CIC-owned, TAF-accredited Advanced Electricity Laboratory (TAF, or Taiwan Accreditation Foundation, is a member of ILAC and a signatory to the ILAC MRA).
For 600-voltage power systems and suited to public utilities and distribution panel builders, these current transformers feature a high-quality coil and a 100% annealed oriented core.
EOS-RN / EOS-RM Series
Current transformers with a Primary Current of 100A~3200A. Burden & Accuracy: 15～30VA/1.0CL. Wiring with insulated wire or a busbar on the primary side. Alternative billing-purpose usage. Many window sizes.
1 core. Rectangular, low-voltage, resin-insulated current transformers for switchgear-panel makers et al. Used with meters. Wiring through a busbar. To be mounted on a busbar or fixed to a switchgear panel.
Low-Voltage Dual-Core Current Transformers (Rectangular Window-Type), for Meters and Protective Uses
2 cores. Rectangular, low-voltage, resin-insulated current transformers for switchgear-panel makers et al. For protection or meters. Wiring through a busbar. Mounting on a busbar or fixed to a switchgear panel.
Split-core, rectangular, low-voltage, resin-insulated protective current transformers for switchgear-panel makers et al. Installing onto an existing power system with ease.
For the need of a higher current ratio and accuracy. A greater window diameter facilitates installation and wiring in a high-current application. Multi-ratio models available. Araldite® epoxy.
These epoxy-insulated, multi-ratio Bushing Current Transformers (Bushing CT), intended for medium-voltage C-GIS, are completely customizable in terms of multi-ratio, burden, accuracy, and dimensions. Standards: IEC and IEEE.
Designed to protect an ungrounded system against leakage and earth faults, these zero-phase current transformers (ZCT) feature an epoxy-cast coil fixed by two metal frames. Window size: 60, 90, 105, 120, or 180 m/mψ.
These are zero-phase current transformers (ZCT) often used with a grounded system for zero-phase current detection and ground-fault protection. Choices of window diameters, current ratios, burdens, and accuracies. Multi-ratio models available. Araldite® epoxy.
ROS Series - ROS-38A, ROS-66A, ROS-78A
For 600V power systems, these resin-insulated Extended-Range Current Transformers offer a Thermal Rating Factor of up to 4.0, while conforming to IEEE C.57.13 and providing a 0.3 Metering Class accuracy.
Outdoor, ring-core (window-type) protective (or monitoring) current transformer for power companies or HV power systems. Converting high AC currents into signals to be received by the relay. Cycloaliphatic Epoxy.
Window-type (split-core), outdoor, protective (or monitoring) current transformer for power companies or HV power systems. Converting high AC currents into signals to be received by the relay. Cycloaliphatic Epoxy.
Designed for energy meters or protective relays, these bushing current transformers can also be used with gas-insulated switchgear or in conjunction with distribution transformers.
