ABB VBSO1-EPD是一个监测系统，用于中高压网络和气体绝缘开关设备中测量漏电流、计数浪涌幅度和分类功能。

SAM 3.0能够灵敏地注册来自闪电和开关的浪涌幅度，与总漏电流相结合。这些值以数字形式显示在电子显示屏上。SAM 3.0由一个可选电缆长度的电流传感器和一个可分离安装的显示设备组成。

It is a monitoring system used for measuring leakage current, counting surge amplitude, and classification functions in medium and high voltage networks and gas insulated switchgear.

SAM 3.0 can sensitively register surge amplitudes from lightning and switches, combined with total leakage current. These values are displayed in numerical form on the electronic display screen. SAM 3.0 consists of an optional cable length current sensor and a detachable display device.
