Product Introduction

The Intelligent Integrated Protection Terminal is designed for short-circuit protection in ring main units or box-type substations, while providing real-time measurement and display of voltage, current, switch status, and other operating data. It is mainly applied to voltage levels of 35kV and below. The device is primarily used for protection, measurement, control, and monitoring in breaker compartments of ring main units and can also cooperate with other devices or systems to form part of a substation automation system.

Key Features

Adopts a color LCD screen with excellent display effect and large viewing area

Four directional keys plus Reset, Return, and Confirm keys enable control of displayed measurement values, operating status, protection information, local tripping tests, and storage/retrieval of protection settings and parameters

Remote testing function supports remote signal point-to-point verification, telemetry testing, and automatic SOE event triggering

Equipped with running indicator and closing/opening position indicators

Equipped with protection trip indicators and alarm indicators

Stores more than 100 historical event records with non-volatile memory (data retained after power loss)

Supports remote closing/opening operation

Provides RS-485 communication interface with open standard communication protocol

Flexible protection function configuration: protection functions can be freely enabled or disabled according to on-site requirements
