Question 1: what is the capacitance of the high pressure sodium lamp? Question two: it's only connected to the light zero line of each lamp. What's the difference between the capacitor and the electric box? Question three: what can happen if there is no capacitive lamp that can be lit?
There is no compensation capacitor, the lamp can also be normal light, only the reactive current is much larger; if there are a lot of no capacitor while using a high pressure sodium lighting bus, so not to allow this bus driving power, line heating, and buck lot, distal lamp without normal light.
This capacitor is locally compensated on each light to reduce the reactive current of the lighting bus, and the centralized compensation on the main junction box does not reduce the reactive current of the lighting bus after the main junction box;
This capacitor is used in reactive power compensation, which can reduce the reactive current of high pressure sodium lamp;
