Product Overview
介损测试仪仪器为一体化结构，内置标准电容器和升压电源，体积小、重量轻，便于携带，具有操作简单、自动测量、读数直观、无需换算、精度高、抗干扰能力强等优点,亦可外接电源与本厂生产的各种规格的高电压等级的标准电容器配套使用，用以测量高压介损。
该仪器是发电厂、变电站等现场全自动测量各种高压电力设备介损正切值及电容量的高精度仪器。能保证在强电场干扰下准确测量。仪器增加了中文菜单功能，操作更为简单，方便。一次操作，微机自动完成全过程的测量。是最理想的介损测量设备。
该仪器同样适用于车间、试验室、科研单位测量高压电器设备的tgδ及电容量；配以绝缘油杯可测试绝缘油介质损耗。
该仪器可用正、反接线方法测量不接地或直接接地的高压电器设备。
仪器内部装备了高压升压变压器，并采取了过零合闸、防雷击等安全保护措施。试验过程中直接加220V交流电源，可输出2KV、5KV、10KV 不同等级的高压，操作简单、安全。
Product Features
Simple wiring (2 wires normal, 1 reverse), all cables shielded, ground-drag usable. Auto ramp, direct reading, no conversion.
Multiple modes: normal/reverse wiring, int/ext std cap, int/ext test voltage.
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) Anti-capacitive rise: auto tracks output voltage, maintains constant test voltage for large-capacity test objects.
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.
