Functional characteristics and technical indexes of harmonic

Zc-630 harmonic analyzer is an instrument developed by our company with the latest technology to measure the three-phase volt ampere electrical parameters. The host can measure the three-phase voltage, current, phase, frequency, power, power factor, three-phase imbalance and other electrical parameters with high precision.

 

 

 

 

Zc-630 harmonic analyzer has the following functions and features:

 

L measure 1 to 3-way AC voltage at the same time;

 

L measure 1 to 3 AC currents at the same time;

 

L measure the phase between voltage, current, voltage and current;

 

L measure three-phase voltage and three-phase current with 1-63 harmonics;

 

L the odd and even harmonics can be displayed separately in the list or spectrum chart;

 

L measurement frequency;

 

L measuring power;

 

L shows the hexagon vector;

 

L three phase unbalance measurement

 

The current amplitude and phase measurement can be up to 1mA at least, which is very suitable for the load test of the main transformer in the substation and the current measurement of the new station or the station with small load.

 

L automatic range switching

 

Full isolation of voltage and current sampling

 

L upgrade application through SD card

 

L use 3.5-inch color LCD

 

L built in large capacity lithium battery, after a charge, when the screen backlight is not turned off, it can work continuously for 10 hours (turn on the backlight off function, and the standby time is longer).

 

Zc-630 three phase harmonic analyzer

 

The following are the detailed technical specifications of zc-630 harmonic analyzer:

 

 

1. Measurement range and error

 

 

Type measurement range unit error resolution

 

Voltage 5 ~ 600V 0.5% x reading + 5 words 0.1V

 

Current 0.001 ~ 6A (expandable) a 0.5% x reading + 5 words 0.0001a

 

Active power 0.005 ~ 3600 w 0.5% x reading (PF = 1) 0.1W

 

Reactive power 0.005 ~ 3600 var 0.5% x reading (PF = 0) 0.1var

 

Frequency: 45 ~ 65 Hz 0.02hz 0.01Hz

 

Phase 0 ~ 360 ° + 1 ° 0.1 °

 

Harmonic ratio 0-10% total harmonic distortion rate error: 0.15% and each harmonic ratio error: 0.1% 0.1%

 

 

2. Working conditions

 

Working temperature: – 20 ~ 50 ℃, relative humidity: 0 ~ 95% non condensing

 

3, power supply

 

The built-in 3.7v/6000mah lithium battery can work continuously for up to 10 hours when the backlight is turned on (with the backlight off function turned on, the standby time is longer). It can also be powered by the 5V / 3A AC power adapter provided with the instrument.

 

 

It can be seen that zc-630 three-phase harmonic analyzer is a new generation of power measuring instrument with multi-function measurement, which is worth purchasing.
