Installation regulations for power system carrier communication coupling capacitors
1 Coupling capacitors should be inspected before installation for cracks in the porcelain sleeve, damage to the porcelain skirt, looseness of the screws in each part, and oil leakage.
The 2-seat capacitor should be installed on the cement foundation or metal components. The grounding body of the cement foundation or metal component should be reliably connected to the grounding grid of the power plant or substation.
3 The grounding terminal of the coupling capacitor should not be less than 2m from the ground. The low voltage terminal is strictly prohibited from opening to the ground.
4 The coupling capacitor must be installed on the outside of the power equipment. It is strictly forbidden to install a circuit breaker between the power line and the power line.
Coupling capacitors installed outside the high-voltage equipment area shall be fenced and marked with the words "high-voltage danger".
The choice of 5 coupling capacitors and power line connection wires should meet the minimum diameter requirements for corona verification.
