Tenders Are Invited For Electrical Equipment And Apparatus – Supply Of Passive Neutral Point Compensators For Low Voltage Public Networks

Electrical Equipment And Apparatus – Supply Of Passive Neutral Point Compensators For Low Voltage Public Networks. This Contract Concerns The Supply Of Passive Neutral Point Compensators Intended To Be Installed On Three-Phase Low-Voltage Public Networks In 3N400v. The Function Of This Equipment Is To Limit The Movement Of The Neutral Point Resulting From Load Or Production Imbalances Between Phases. They Help To Improve The Balancing Of Phase-Neutral Voltages, To Reduce Voltage Differences Between Users Connected To Different Phases And To Maintain The Quality Of Network Supply. The Compensators Will Be Connected In Bypass To The Existing Network And Must Operate In An Entirely Passive, Continuous And Autonomous Manner, Without Power Electronics, Without A Control System And Without Auxiliary Power Supply. The Solutions Proposed May Be Based On A Zigzag Type Magnetic Coupling Or On Any Equivalent Passive Technology Making It Possible To Achieve Identical Performances In Terms Of Stabilizing The Neutral Point And Improving Voltage Balancing. The Equipment Must Be Suitable For Permanent Operation On Low-Voltage Public Networks, Have A Robust Design Compatible With Outdoor Installation And Meet The Requirements Of Reliability, Safety, Dielectric Strength And Resistance To Environmental Constraints Applicable To Electrical Distribution Equipment. The Expected Performances Concern In Particular The Limitation Of The Movement Of The Neutral Point, The Improvement Of The Balancing Of Network Voltages, The Reduction Of Voltage Imbalances And The Maintenance Of The Quality Of Supply Under Normal Operating Conditions.
