ETCR5500 Phase Change Switch Type Three Phase Unbalance Correction Device -etcr

ETCR5500 Phase Change Switch Type Three Phase Unbalance Correction Device

Product Function

1. Equal voltage 0ms seamless phase change technology , phase changing will not interrput the power supply;

2. There is not inrush current in phase changing process , stable and reliable;

3. Precise posisioning phase converter ensure the balance of each branch of the distribution network hop by hop ;

4. No adverse effects on all kinds of electrical equipment。



Phase swapping type three - phase unbalance correction device compose by the main controller and phase converter. The main controller is responsible for collecting the real-time load data of the transformer area; analyze the load voltage and current of each phase converter; Form and send command to the phase converter. The phase converter receives and executes command from the main controller. The main controller and the phase converter wireless communicate by 230MHz.One main controller and several phase converter can be configured according to the LV transformer areas capacity and the severity of imbalanceDuring installation, it can be used with the ETCR1100 phase  line identify meter in low-voltage transformer areas to identify phase A, B, and C phase lines in the station.









Product Feature

1. Equal voltage 0ms seamless phase change technology, phase changing will not interrupt the power supply. Phase changing time is 0ms, precise and controllable. The phase changing process is completed by the power electronic device, no mechanical contact and will not generate ARC. After phase change, the permanent magnet switch keep a steady state without loss.

2. There is no inrush current in phase changing process, stable and reliable. Since the commutation time is 0ms, the phase jump of 120° is only at the moment when the voltage of the two phases is equal, which belongs to natural commutation, so there is no voltage mutation or inrush current.




3. Precise positioning phase converter ensures the balance of each branch of the distribution network hop by hop. The unique hop by hop voltage drop synthesis algorithm, priority to adjusting the phase converter closest to the extreme value of line unbalance degree, thus ensuring the optimal balance degree of each part of the line, reducing the neutral line current more effectively and improving the terminal supply voltage.

4. No adverse effects on all kinds of electrical equipment. Equal voltage 0ms seamless phase changing technology will not cause power supply interruption and voltage sag, and will not influence the user's electricity consumption. Stable and reliable phase changing for inductive, capacitive and resistive load.
