GFEVT-C1-10 RING MAIN UNIT 12KV INDOOR ELECTRONIC VOLTAGE TRANSFORMER
INTRODUCE
The GFEVT-C1-10 series of electronic voltage transformers is a capacitive voltage divider structure, epoxy resin casting, fully enclosed insulation, safe and reliable, suitable for voltage measurement (metering) and protection in equipment with a maximum voltage of 12 kV and below AC 50/60 Hz power lines. This product has the characteristics of high precision and large capacity, and can be customized according to customer requirements. It is used by Air insulation cabinet, as protection voltage transformer and measurement voltage transformer in less than 12KV power system. It was designed with reasonable structure and robust construction.
All of our indoor voltage transformers are strictly comply IEC60044-7, IEC 61869-6, ANSI/IEEE C57.13, GB1207-2006, GB/T 20840.7, GB/T 22071.2-2017, GB/T 20840.102-2020.
FEATURES
IEC60044-7; IEC 61869-6; ANSI/IEEE C57.13 standard; Rated voltages up to 12kV; Rated basic insulation levels (BIL) up to 75kV; The windings are copper wire with copper plate double isolation; Partial Discharge measurements exceed the IEEE/IEC and CAN/CSA requirements; Measuring and protection class using; Can achieve measurement of phase sequence or zero sequence voltage and sampling of protection signals; The secondary output is a safe low voltage signal, greatly reducing power consumption and generating less heat; No ferromagnetic resonance, no need to configure fuse protection; No risk of secondary short circuit and high current, increased safety; Can measure DC and low-frequency AC signals; Product standardization, simplified selection and ordering process, and fast delivery; Small size, light weight, and easy installation; Combined with multifunctional intelligent feeder terminals (FTUs), these excellent features will bring great improvements to power protection and monitoring; Accuracy class: 0.2, 0.5, 1, 3, 3P, 6P; Rated voltage ratio (KV): 3KV/√3, 6KV/√3, 10KV/√3 or 11KV/√3/3.25V/√3/6.5V/3; Weight: 2KG;
