Product features
1, system-off voltage of zero (N) phase difference automatically relay function (select function ON / OFF)
(1) adapted to the supply and distribution the grid region shunt system off zero (N), because of uneven load of the respective phases, resulting in each phase of the phase offset, resulting in the phase voltage of the difference is greater than the rated voltage of> 10% amplitude, when the system phase voltage deviation ≥ 13%, the VDP monitoring system became an instant issue voltage differential protection function instruction role will shunt off the zero-loop system to force the withdrawal of grid operation. To ensure that the general public and the electricity user, The all power facility will not be burned to protect the community safe use of electricity system off zero loop.
(2) When the power supply system off zero (N) Troubleshooting perfect repair, restore normal power supply, the the TLP-III controller detects normal supply of electricity to the grid system, the device will automatically reclosing to restore the system to be protected the grid normal power supply, ensure that users safe use of electricity.
2, the power distribution network system missing phase relay
(1) applies for the power distribution system three phase power supply to run, put into operation or running, the system network suddenly appeared missing running. At the moment due to the controller built-in VDP detection device, system power voltage three-phase vector and not equal to zero (the differential voltage sample-taking time ≤ 1.5s); became an instant issue lack of protection directive role, will shunt the power to force the withdrawal the grid operation, to ensure that the electricity facilities will not be damaged due to missing running.
(2) for the power distribution system, lack of phase, fault processing is completed, the network returned to normal operation, the the TLP-III controller detects the grid voltage phase normal three-phase vector and is equal to zero, the device will automatically reclosing restore normal power supply protection system grid, to ensure that users safe use of electricity.
