Hebei Kepin Electric KPFT-2T Small Current Grounding Selector Unit User Manual
The KPFT-2T is a micro‑computer grounding selector designed for single‑phase ground fault detection in 3 kV–66 kV power plants and substations.

The manual describes system parameters, line settings, data queries, and time adjustments via the front‑panel keys, as well as communication options (RS‑232/RS‑485) and wiring diagrams for installation. It also lists the hardware dimensions, power requirements, and a full catalog of zero‑sequence current transformers that can be connected. This manual is written in Chinese.
