Fourier transform digital filtering technology for precise capacitance and dielectric loss measurements, enabling automatic and accurate results.<\/li>\n<li>Frequency conversion technology in the instrument eliminates 50Hz power frequency interference, ensuring reliable data in areas of strong electromagnetic interference.<\/li>\n<li>The full touch LCD is user-friendly, with a comprehensive graphical interface that makes the operation clear and simple, allowing operators to measure processes via touch without specialized training.<\/li>\n<li>Data storage is facilitated by a calendar chip and ample memory, allowing for immediate result saving, historical record viewing, and printout with current and logged times<\/li>\n<li>The instrument&#8217;s operation and easurement process is microprocessor-controlled, automating data measurement once the correct mode is selected.<\/li>\n<li>The integrated design includes a standard capacitor and high-voltage power supply, making field testing convenient and reducing on-site wiring.<\/li>\n<li>The instrument&#8217;s high accuracy fulfills the requirements for measuring oil dielectric loss, necessitating only a standard oil cup and tesing line.<\/li>\n<li>It features low-voltage shielding for reverse wiring, allowing for dielectric loss measurement of 110 kV reverse wiring under 220 kV CVT bus grounding without disconnection.<\/li>\n<li>It can conduct AC voltage withstand tests, useful for PT and CT secondary voltage endurance tests and 400V low voltage systems.<\/li>\n<li>The instrument recognizes external high-voltage power supply frequencies from 40Hz to 70Hz, accommodating large capacity and high voltage dielectric loss tests with power frequency or series resonant power supplies.<\/li>\n<li>It has a CVT test function, enabling self-excitation tests with four high\/low voltage\/current protection settings for safety.<\/li>\n<li>When testing CVTs, it automatically measures the capacitance and dielectric loss of C1 and C2, as well as the total values for the equipment.<\/li>\n<li>It includes a thermal printer for immediate report generation, with a built-in calendar and USB output for convenience.<\/li>\n<li>Grounding protection prevents high voltage output when grounding is insufficient or absent, and overcurrent protection safeguards the instrument against sample short-circuits or breakdowns.<\/li>\n<li>An electric shock protection feature immediately cuts off high voltage in case of operator contact, ensuring tester safety.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong><b>Technical Specifications:<\/b><\/strong><\/p>\n<p><strong><b>\u00a0<\/b><\/strong><\/p>\n<table>\n<tbody>\n<tr>\n<td rowspan=\"2\"
