Voltage current transformer applications

Capacitive pressure machine available in high pressure and ultrahigh pressure used to measure the motor vehicle spare parts voltage and the power is in the power system, electric energy metering, relay protection and automatic ac electric motor control, etc., and can double as coupling capacitor is used for power line carrier communication system. If you have any requirements, can provide for harmonic voltage measurement of internal and external terminals. (1) the installation run place: indoor or outdoor. (2) above sea level: product no more than 330 kv and below 2000 m. 500 kv products no more than 1000 m, according to the order, can offer until 4000 m plateau type products. (3) temperature: - / + 40 degrees, 40-25 / + 45 degrees. Selected by the user in order (also can choose other temperature classes). 


(4) wind speed: not more than 42 m/s. (5) pollution level: Ⅰ level electrical motor filthy (outer insulation creepage distance 17 mm/kv or higher); Filth Ⅲ level (outer insulation creepage distance 25 mm/kv or higher); Filth Ⅳ level (outer insulation creepage distance 31 mm/kv or higher). Pollution level in by the user to choose when you order it. (6) ice thickness: not more than wholesalemotor.blogspot.com 10 mm. (7) seismic intensity: no more than 8 degrees. According to user requirements, also can provide higher seismic ability of the product. Rated frequency (8) systems: 50 hz or 60 hz have users in order is determined. (9) system earthing conditions: neutral point grounding or neutral not effective effectively; Be determined by the user in order.
