JouYang Electrical: potential transformer manufacturer and potential transformers design in China.

Established in 1990, China JouYang Electrical Products Co.,Ltd. is known as a leading potential transformer manufacturer and designer of high and low-voltage electric appliance in China. We integrate scientific research, development, production, sale and service in one company. Our custom potential transformers products are characterized by their superior dustproof, splash-proof, anticorrosion, fire-resistant, thermo-stability and aging-resistant properties. Having received ISO9001 certification for our manufacturing and sales systems, we have also been issued European 'CE' and Chinese 'CCC' safety authorizations for our products. All of our OEM potential transformer products are strictly according to IEC/GS/EMC/LICE/UL/CSA standard and guaranteed by People's insurance Corporation of China (PICC).

Traditional, window type current transformers for measuring 50-400HZ currents of 5A to 15000A with secondaries of 0.1A, 1A and 5A (special secondary currents are available). Burden: B 0.1 through 1.8 (2.5VA to 50 VA) with Accuracy class: 0.2 to class 5.0 as per IEC 185 or class 0.3, 0.6 or 1.2 as per ANSI C 57.13. Inside diameters of up to 8.00". Many models are available as U.L. recognized devices. potential transformers for various voltage, frequency and physical size ranges. We have broken them up into several different groupings: low voltage, which are system voltages under 15kV; high frequency, operating frequency over 1kHz; and size ranges from board mount parts up to current transformers with window sizes of 254mm by 610mm. Read through the different types we supply below and use our Instrument Transformer RFQ Form to request a specific part to meet your requirements. Applications include:
UPS systems
Transfer switches
Motor-generator sets
Commercial sub-metering,
3 CT 's in one package for 3-phase metering
Accurate measuring for metering/WATT/VAR

The AYA Metering Potential Transformers are designed for monitoring single-phase and three-phase power line voltages in power metering applications. The primary terminals can be connected either in line-to-line or in line-to-neutral configuration. Fused transformer models are designated by a suffix of "F" for one fuse or "FF" for two fuses.
These are used with a system voltage 3.3kV to 25kV and BIL 4.5 to 125 full wave crest kV. They are reliably constructed using vacuum cast with epoxy resin/polyurethane resin and are able to withstand heavy fault conditions but are not made for exposure to sunlight. Single CT's can be built with multiple cores; for example — one for measuring and another for relaying are possible. Also multi-tap secondaries can be provided (up to 4). Typical primary current 5 Amp to 3000 Amp. Current sensing, recording, monitoring & control. Control panels and drives. Standard CT used as measuring standard for comparison. Winding temperature indicator (WTI) for power transformers. Summation current transformers.
