Dielectric Loss TesterFeatures
1、变频抗干扰
采用变频抗干扰技术,在200%干扰下仍能准确测量,测试数据稳定,适合在现场做抗干扰介损试验。
2、高精度测量
采用数字波形分析和电桥自校准等技术,配合高精度三端标准电容器,实现高精度介损测量。
仪器所有量程输入电阻低于2Ω,消除了测量电缆附加电容的影响。
3、多级安全保护,确保人身和设备安全
High-Voltage Protection: In case of specimen short circuit, breakdown, or high-voltage current fluctuation, the output can be cut off at high speed via short-circuit method.
Low-Voltage Protection: Protection is activated in case of mistaken 380V connection, power fluctuation, or sudden power failure, preventing overvoltage.
Grounding Protection: When poor grounding causes the enclosure to carry dangerous voltage, grounding protection is activated.
C V T:高压电压和电流、低压电压和电流四个保护限,不会损坏设备;误选菜单不会输出激磁电压。CVT测量时无10kV高压输出。
