LMZP‑10 10kV Rectangular Window Through‑Core Current Transformer for Busbar
Model and its meaning

Summarize
The through-hole run-shaped window current transformer (also known as the high-precision current transformer) is suitable for electric energy metering, high-accuracy limit protection and current measurement in the 10kV to 35kV power supply system of the AC power system. This type of current transformer is designed for the metering and high-limit protection of the incoming and outgoing lines of the cables in ring main units and switch stations. It can be run through two or more cables, perfectly solving the problem of multiple outgoing lines. It can replace the high-voltage busbar type metering transformer (LZZB series). The product is small in size and has high metering accuracy (0.2M grade). It is a full-condition product and can operate in various environments. It is a maintenance-free product that can reduce equipment space, lower costs and enhance reliability. It is applied to fully insulated and fully sealed compact models such as Safeplus, SM6, 8DH, FB, GA/GE, SS and FIT.Based on the differences in current variation, accuracy level and rated load, this series of transformers is divided into the following types. For specific parameters, please refer to the corresponding parameter table of each type.
The main features of the LMZP-10 through-core track-shaped window current transformer include:
High-precision measurement: The LMZP-10 has excellent measurement accuracy and can accurately convert large current signals into small current signals, thereby ensuring the safety and stability of the power system.
