Turns ratio tester of ZC-203E finishes test of three-phase voltage ratio or turns ratio once, fast testing and high precise.
|Resolution||Minimum is 0.0001|
|Working power supply||AC220V±10% 50Hz|
|relative humidity||≤85%, non-condensing|
1.Sampling digital three-phase inverter test power supply, no harmonic content, voltage easy to adjust, start, stop to eliminate the AC220V or sampling generator power supply impact.
2.Three-phase test power supply, improve the test speed, can identify the transformer wiring group 0-11.
3.Applicable to a wide variety of transformers, with a z-shaped connection transformer test function.
4.After one input of rated parameters, transformer transformer ratio, error value and tap tap location can be automatically measured. For tap switches with asymmetric tap switches, the exact position of the tap switch can also be accurately measured. Tap switches with up to 197 tap points can be measured.
5.Protection function is perfect, with high and low voltage reverse connection protection, transformer between turns short circuit protection, output short circuit protection, increase the stability of the use of the instrument.
6.Adopt 7 inches 65K color touch screen liquid crystal, imitate mobile phone to change liquid crystal display way, operate simply and quickly.
7.The instrument has power clock and data storage, which is convenient for viewing historical data.
8.The instrument has both print output and U disk interface, and also can be equipped with RS232 interface, which is convenient for paperless office.
9.Adopt cold and temperature resistant, sealed and waterproof, anti-fall and shockproof multi-functional engineering plastic box, which is convenient for field test.
