INTRODUCTION

MEWOI-4520C series High Performance High Voltage Insulation Resistance Tester is a high performance high voltage insulation resistance tester of well research and development by our company. The instrument has perfect testing function of various insulation resistance parameters and excellent anti-interference ability, whichcan be used to test the insulation resistance of large capacity high voltage electrical equipment and transmission lines in substation with strong induction electric environment. The instrument adopts true color touch screen, and all the test data and battery power are displayed on the same screen for viewing clear and obvious. The combination of knob switch and button makes the operation very simple. The user does not need to memorize the operation method, but just click "HELP" on the screen to pop up the operation method, effectively guiding the user to operate the instrument. The instrument has the function of rapid discharge, the charge of the tested object is released automatically after the test. The voltage monitor of the instrument automatically monitoring the live voltage of the measured object, when the voltage exceeding 36V will automatically prohibits testing and effectively protects the instrument and operator.

The instrument adopts large capacity rechargeable lithium battery pack. The test timer of the instrument automatically records the test time and stores the test results with date and time. The touch screen can easily check the historical data recorded. The fully isolated USB interface can upload the test data to the PC safely. The instrument is equipped with the test line with double insulation and shielding layer, and the high voltage rod is equipped with replaceable crocodile clip and hook, which can adapt to various test places. The instrument adopts a strong double-shell structure, and the outer case of the instrument has a protection rating of IP65, which can prevent the intrusion of moisture and dust as well as prevent to impact in the transportation and storage process, effectively protect the instrument.

MEWOI-4520C series High Performance High Voltage Insulation Resistance Tester with a wide measurement range, high resolution, convenient operation, strong and durable, accurate and reliable, stable performance and strong anti-interference ability. The instrument with insulation resistance test (IR), polarization index test(PI), dielectric absorption ratio test (DAR), ramp test mode (RAMP), Dielectric discharge (DD),filtered resistance test mode (FR 10S?20S?30S?40S four selections), voltage test (V), capacity measurement (uF), current measurement (nA) and others function. The instrument is suitable for testing the insulation resistance of large equipment such as electric equipment which with large capacity, high voltage and in strong induction electric environment, and transmission line, which is the power, telecommunications, meteorology, computer rooms, oil fields, mechanical and electrical installation and maintenance and power supply departments of industrial and mining enterprises commonly used but essential instruments.
