Product Details

全自动抗干扰介质损耗测试仪是一种新颖的测量介质损耗角正切值（tgδ）和电容值（Cx）的智能化仪器。可以在工频高压下，现场测量各种绝缘材料、绝缘套管、电力电缆、电容器、互感器、变压器等高压设备的介质损耗角正切值（tgδ）和电容值（Cx）。

Product Features

n 自动简单 接线简单（正接法两根线，反接可使用一根线），所有电缆线均有接地屏蔽，所以都能拖地使用，测量电压缓升、缓降，全自动测量，结果直读，无须换算。n 多种测量方式 可选择正/反接线、内/外标准电容器和内/外试验电压进行测量。正接

HV D/L measurement capable

Anti-vibration: withstands strong vibration during transport.

Strong anti-interference: auto tracking compensation, vector+phase shift, eliminates E-field interference for 500kV substation tests.

TBD

Safety: (1) HV protection: rapid cut-off on short, breakdown or current fluctuation.

(2) CVT protection: auto exit on overcurrent setpoint, no damage.

(3) Ground detection: cannot boost without proper grounding.

(4) Anti-misoperation: detects common wiring errors, safety alarm.

（5）防“容升”：测量大容量试品时会出现电压抬高的“容升”效应，仪器能自动跟踪输出电压，保持试验电压恒定。

VFD display: large dot-matrix, clear in all seasons. Full Chinese

Chinese menu with warnings, intuitive, no manual needed.

Print: built-in micro printer for Chinese results and status.

RS232 for PC connection for data processing and saving.

Optional PC communication software available.
