Functions of each key of relay protection vector analyzer

Zc-650 relay protection vector analyzer is also known as six phase protection loop vector tester and loop vector analyzer. It can complete high-precision measurement of three-phase voltage, current, phase, frequency, power, power factor, three-phase imbalance and other electrical parameters with a single host.

 

 

Zc-650 relay protection vector analyzer has 11 keys, which are F1, F2, F3, F4 four function keys, menu key, enter key and ↑, ↓, ←, → four direction keys, key power on key. It is described as follows:

 

1. F1, F2, F3, F4 function keys:

 

The definition of the four function keys may be different under each interface, and the specific definition has a text prompt in the corresponding area of the LCD screen.

 

2. Menu key:

 

The function of this key is to return the instrument to the “main menu” interface. No matter what state the current instrument is in, the instrument will enter the “main menu” interface after the key is triggered. The user can select the required function to operate again in this interface.

 

3. Enter:

 

The function of this key is to confirm the input or confirm the option. The use of this key will be specified in the instructions for each function.

 

 

4. ↑, ↓, ←, → direction key:

 

They are up / down / left / right direction keys. These keys are used to change options, parameter setting values, page turning, etc. for the use of these keys, please refer to the specific instructions in the use instructions of each function.

 

5. Key power on key:

 

This key is the instrument power control key. In the shutdown state, the user presses for about 3 seconds, and the instrument will be powered on. In the power on state, the user presses the key for about 3 seconds, and the instrument will power off.

 

 

Zc-650 relay protection vector analyzer completely solves the problem of distributed synchronous measurement in the substation. It does not need GPS and cable to introduce reference voltage, and avoids PT secondary short circuit caused by cable insulation or operation problems. It is simple and practical, which is worth purchasing.
