ZXTQ-202 good performance Two Way Transformer Area User Identification Device

The device is composed of the main machine and hand hold terminal. The main machine is installed at the distribution transformer three phase low voltage side, hand hold terminal is hold by census staff at user side.

It adopts Impulse method and power line carrier signal method for area identification. The two methods can be combined to use or used independently

It can store the tested user properties, analyze the saved data, directly display every area, every phase user quantity and total user quantity. At the same time it can real time measure and display power system harmonic and waveform

Features:

1. Can measure user wire connection situation and identify the transformer and phase
2. When carrier signal can’t be transmitted to the terminal due to long distance or some other reasons, the terminal can send impulse current signal and the main machine receive the signal for identification of user area and phase
3. Can analyze the testing data and tell transformer load of every phase ( energy meter numbers)
4. Display and store voltage value of the tested line and measure the voltage difference between transformer exit terminal and user terminal
5. Display line 3~51th odd order harmonic content, and save total harmonics of the tested line
6. Display voltage waveform the tested line
7. Can use 3 clamp meters to test when it is difficult to identify the zero line
8. The master can display electric parameters when use the three clamp meters
9. Can use one clamp meter to detect the terminal impulse signal on zero line, to identify user area when the on line current is over 200A
10. Can arbitrarily set area number to distinguish the tested transformer
11. No need to discriminate the direction or polarity for impulse method testing no matter it is the terminal voltage wiring or the master current clamp wiring
12. Menu reminding the testing process and results, simple to operate

Technical indicators:

1. Working voltage: the main machine AC 3*220/380V, hand-held terminal AC 220V
2. Frequency: 50Hz
3. Working temperature: -10～+45℃
4. The main machine power dissipation: each phase ≤2W
5. Hand-held terminal power dissipation: ≤1W ( when no impulse current sending )
6. Hand-held terminal maximum transient impulse current: 10A
7. Working radius: carrier communication < 2.7km, impulse current method > 5km
