Product introduction
With digital synchronous sampling techniques, accurate measurement of three-phase power equipment voltage, current, power, power factor and other parameters of the true RMS, with high speed, high precision, easy to use, lightweight and beautiful, etc. features. Specifically applied to the detection of power transformer, the meter can be replaced at the same level nine pointer instrument, is the traditional power of the test instrument ideal replacement product.
Also called name
Transformer loss parameter tester, transformer loss parameter detector
The Characteristics of the products
1.A measurable types of transformer load current, load loss, impedance voltage, short circuit losses.
2,Limit the amount of voltage loop width: Maximum measuring voltage 750V, without switching gears to ensure accuracy. Choose the wrong voltage will not stall while the instrument itself is damaged.
3,Large-screen, high brightness LCD display, full English menu and operating tips to achieve a friendly man-machine dialogue, easier to operate.
4,The user can print out the test data in real time.
5,The use of digital synchronous sampling techniques, accurate measurement of three-phase power equipment voltage, current, power, and other parameters of the true RMS measurement accuracy of 0.2.
6,NABDS transformer loss parameter tester can be replaced by a pointer to the same level of nine meters, is the traditional power of the test instrument ideal replacement product.
The parameters of the products
1, The input characteristics: Voltage measuring range: 0 ~ 750V wide quantity is limited.
Current measuring range: 0 ~ 100A internal autoranging.
2, Accuracy: voltage, current: ± 0.2%
Power: ± 0.2% (COSΦ> 0.1), ± 0.5% (0.02 3, Working temperature:-10C ~ +40 ℃

Attention should take
1. Don’t touch the metal parts during the measurement test to avoid electrically damaging.
2. Wiring must be strictly measured by manual operation.
3. Be sure to carefully check before the test parameters set correctly.
4. Best to use a grounded outlet.
5. Do not limit the voltage and current in case excessive work.
6. Short circuit test, the non-pressurized side must be well short, or would affect the test results.
7. Do short-circuit test, if high or medium voltage side with an annular bushing current transformer, current transformer before testing the secondary side must be shorted.
8. Test wiring work must be grounded in the test line in the case, to prevent induced voltage electric shock. All short circuit, grounding and wire should have sufficient cross-section, and must be firmly connected. Test organization working to tight, smooth communication, in order to ensure the smooth progress of work safety testing.
