绝缘测试器3108 MI EurotestPV

RCD 电压 回路阻抗

MI 3108 EurotestPV是一款光伏测试仪和电气安装安全测试仪。它能够根据EN 61557标准进行电气安装的完整测试，此外还能执行单相光伏(PV)安装所需的所有必要测试。这包括en62446要求的所有测试，但也包括I - U特性，en61829要求的STC值计算和逆变器直流和交流侧的功率测量。该单元设计用于苛刻的工作条件(高达1000v, 15a直流)。为了大大提高用户的安全性，MI 3108 EurotestPV配备了PV安全探头，确保每次安全断开连接。测量功能光伏安装:•测量光伏安装的直流侧:•电压、电流、功率;•Uoc(开路电压)和Isc(短路电流);•光伏组件和光伏串的I - U曲线;•辐照度;•温度模块。 • Measurements on AC side of PV installation: • Voltage, current, power; • Efficiency of PV module, inverter, PV system calculation. Electrical installations: • Insulation resistance; • Continuity of PE conductors; • Line impedance; • Loop impedance (sub-functions with high current and without RCD tripping); • RCD testing (type AC, A and B); • Earth resistance; • AC current (load and leakage); • TRMS voltage, frequency, phase sequence; • Power, energy, harmonics.
