Product Details
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:
- Can measure user wire connection situation and identify the
transformer and phase
- 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
- Can analyze the testing data and tell transformer load of every
phase ( energy meter numbers)
- Display and store voltage value of the tested line and measure the
voltage difference between transformer exit terminal and user
terminal
- Display line 3~51th odd order harmonic content, and save total
harmonics of the tested line
- Display voltage waveform the tested line
- Can use 3 clamp meters to test when it is difficult to identify the
zero line
- The master can display electric parameters when use the three clamp
meters
- 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
- Can arbitrarily set area number to distinguish the tested
transformer
- 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
- 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
