GWPR100-AIP Low-Voltage Anti-Islanding Protection Relay

The GWPR100-AIP low-voltage anti-islanding protection relay is mainly applied to medium- and small-sized 400 V distributed photovoltaic grid-connected cabinets. It integrates protection, measurement & control, communication and event recording functions. The device can be mounted in switch cabinets in a distributed manner or centrally panel-mounted, and is suitable for anti-islanding and comprehensive protection of low-voltage PV grid-connected systems.
Equipped with one RS485 port adopting the Modbus-RTU protocol. Communication address, baud rate and parity bit are configurable. It can connect to a supervisory host system to upload measured analogs, binary status, events and protection settings.

GWPR200-AIP Anti-Islanding Protection Relay

GWPR200-AIP Anti-Islanding Protection Relay is designed for distributed photovoltaic power projects at 11kV and 22kV voltage levels. It is a digital protection relay specially developed to prevent islanding conditions.This relay can be used with the GWPR200-FL Grid Fault Disconnection Relay and GWPR200-D Power Quality Online Monitor to form a grid-connected protection panel, or flush-mounted on the panel of the PV grid-connected cabinet.

Communication Interfaces:

2 Ethernet ports (supporting IEC 60870-5-103; optional)
1 RS485 communication port (supporting Modbus-RTU protocol)
Time synchronization via communication message, SNTP, and IRIG-B
