TSP model solar phase control


**[Sant phase control TSP model:](https://www.automation24.ir/product-3335/%DA%A9%D9%86%D8%AA%D8%B1%D9%84-%D9%81 **

## To protect three-phase motors against disconnection of phases - decrease or increase of network voltage - displacement of phases - asymmetry of voltage in the three-phase network. If any of the problems mentioned above occur in the network voltage, this relay It cuts the output so that the devices connected to it are not damaged.
## This device has a potentiometer to adjust the percentage of voltage error from 8 to 30%, as well as a potentiometer to adjust the delay from 4 to 15 seconds.
phase control:
This device is designed to protect three-phase motors against excessive decrease or increase of network voltage, phase disconnection or phase displacement, and in many cases, the cause of motor burning is incomplete connection of contactor contacts. As a result, the phase control is installed after the contactor.

Phase control function:
After three phases and neutral are connected to terminals L1, L2, L3 and mp, if the voltages are suitable and the phase sequence is correct, the u indicator will light up. If the sequence of phases is not correct (the PH indicator turns on), this problem can be solved by changing the place of the two phases, and after the delay time passes, when the RLY light turns on, the contact 15 of the relay is disconnected from 16 and connected to 18. If there is any problem in the network, the corresponding indicator lights up. Internal relay RLY turns off.
Relay settings:
There are two adjustment screws on most of the phase controls, which are as follows:

Reaction time: With this adjustment screw, the cut-off delay time can be set, which is used to cover the start time and prevent the relay from operating in unfavorable situations.

Phase disconnection sensitivity: With this adjustment screw, asymmetry and return voltage can be selected in the direction of output disconnection. (In most cases, a sensitivity between 15 and 20% is suitable, but in motors that have a high return voltage, a sensitivity of 5% can be used, and if the voltage asymmetry in the network interferes with the normal operation of the relay, a sensitivity of 25 to 30% can be used. did.)

The difference between phase control and phase supercontrol:

Phase control of high voltage, low voltage and asymmetry parameters is fixed and unadjustable, but it can be adjusted in phase super control.

The neutral wire is for network symmetry and also if the neutral wire is energized, the phase control works and cuts off the system.

Finally, to ensure the sound of the relay setting, you can cut off the fuse of one of the three phases while the engine is running, so that the network becomes two-phase and the phase control relay works.

Application of phase control:

### Detection of disconnection or two-phase main electricity
### Detection of phase sequence change
### Disconnecting the circuit if the three-phase voltage is not symmetrical
### voltage drop
### Voltage increase
### Disconnection of the circuit in case of shocks caused by consecutive disconnection and connection of electricity
### The ability to choose the connection time after fixing the error
