1.When the capacitor is installed, the wiring of each capacitor is best connected with the bus bar, and the hard busbar connection is not used in order to prevent the assembly stress to cause the damage of the capacitor bushing and destroy the oil leakage caused by the seal.
2.Any undesirable contacts in the capacitor circuit may cause high-frequency oscillatory arcs, which increase the electric field intensity of the capacitor and cause damage to the heat. Therefore, the contact between the electrical circuit and the grounding part must be kept well during installation.
3.When the lower voltage level capacitors are connected in series to the higher voltage level network, the insulation between the units of each station should be reliably insulated by adding insulators equal to the operating voltage level.
4.When the capacitor is connected by star connection, it is used for high grade rated voltage and the neutral point is not grounded.
5.Before capacitor installation, a capacitor should be allocated to balance the phase, and the deviation should not exceed 5% of the total capacity. When a relay protection device is installed, it is also necessary to satisfy the requirement that the balance current error of the operation does not exceed the protective current of relay protection.
