LXQ (LXQ3, LXQ4) type nonlinear resistance harmonic eliminator (harmonic eliminator for short) for neutral point of voltage transformer is installed in primary winding (or secondary winding) Y of 6~35kV voltage transformer (PT for short). A nonlinear resistance harmonic damping device between the neutral point of the junction line and the ground. Compared with the traditional RXQ type harmonic eliminator, the LXQ type harmonic eliminator has been greatly improved in design to improve the thermal capacity of the harmonic eliminator. The harmonic eliminator has superior electrical performance.

The role of drop-out fuses10kV equipment can be installed on the high-voltage side of the transformer on the pole, where the transformer and capacitor are connected to the line. The drop-out fuse can effectively protect the circuit from overload and short-circuit. At the same time, it can also be installed at the end of a long line or on a branch line, which can provide extended protection for areas that cannot be protected by relays.
