TDB automatic capacitor bank can reducing harmful system harmonics and therefore fewer occurrences of power quality-related equipment problems. Ability to free up spare capacity on the transformer and main switchboard, thereby providing additional capacity for future load growth without the need to upgrade infrastructure. More stable and improved voltage regulation ensuring motors and plant operate at maximum efficiency. Reducing strain on the network provider's supply system thus helping avoid possible blackouts in the area. Features ·Used adaptive self-healing electrical capacitor, high reliability, long operating life and can work in low running temperature. ·Imprvoe power factor, reduce reactive power loss, has evident effect for power conservation; ·Upgrade power quality, balance transformer load factor and electrical equipment efficiency; ·With short circuit protection, control device can automatic disconnection power if there will be internal fault, ensure the equipment safety operation; ·With self discharge circuit, after switching off from the power grid, residual voltage will decline below 50V in three minutes; ·Reasonable structural design, stainless steel cabinet have good thermal and dynamic stability.
