By using the control of the siva phase of the waves, it is possible to control the power grid disturbances. Disturbances caused by voltage increase or decrease and asymmetry of phases are indicated by F indicator and displacement by P indicator.


Characteristics of the phase control of Shiva waves

Accurate control of the electrical network due to the non-use of neutral (energization of the neutral in some cases)
Protection against:
Increase and decrease voltage
Non-sequence (displacement) and asymmetry of phases
Interruption of any of the phases
4 indicators for announcement
AC: mains electricity
REL: Connect the relay
F: increase and decrease of voltage and asymmetry of phases
P: Non-sequence (displacement) of phases
Adjustment screws to adjust asymmetry and connection time
The parameters do not change due to the impact of the panel contactor

The difference between phase control and phase supercontrol:

Phase control of high voltage, low voltage and asymmetry parameters is fixed and unadjustable in itself, 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.


phase control:

This device is designed to protect three-phase motors against excessive reduction or increase of network voltage, phase disconnection or phase shift, and in many cases, the cause of motor burnout is incomplete connection of contactor contacts. As a result, the phase control is installed after the contactor.


Phase control function:

After three phases and zero 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. In case of any problem in the network, the corresponding indicator will light 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: time can be adjusted with this screw
