Product Description

Photovoltaic grid harmonic measurement monitoring control Vertical Microcomputer Anti-Island Protection Large Size

Islanding is a phenomenon where a photovoltaic power station continues to supply power to a part of power grid that has lost voltage. For small photovoltaic power stations, it is important to have the ability to quickly monitor and immediately disconnect from the grid in the event of islanding While most photovoltaic inverters have antiislanding protection, it is recommended to install an additional antiislanding protection device at the grid connection point for safe, stable, and reliable operation of the power system. It can quickly cut off the distributed island power supply. and also has the capability to automatically close when the system voltage is normal, according to user requirements

LDGD800 Microcomputer AntiIsland Protection series utilizes a specially designed microcomputer device and control circuit to ensure rapidity protection action and accurate control. It can be centrally grouped into panels or installed in switch cabinets in a decentralized manner, with communication achieved through a 485 bus.
This device monitors the lowvoltage side of the distribution transformer in real time, performs necessary control on the clean power supply, and prevents unplanned islanding.
