UNI-T UT515A Digital megohmmeter 10KV Digital Insulation Resistance Tester High Voltage Resistance Multimeter with Absorption Ratio and Polarization Index Measurement

UT515A10KV Insulation resistance tester This is a digital high-voltage insulation resistance tester with 6 ranges: 250V, 500V, 1000V, 2500V, 5000V and 10000V. It allows fine-tuning voltage with a 10% step. Test data can be saved in the instrument’s memory and transferred to a PC via a USB cable. It is widely used to measure insulation resistance in transformers, cables, and electrical equipment, as well as in high-voltage power, telecommunications, meteorology, and oil fields.

• 【UT515A Digital Megohmmeter】UT515A Digital Insulation Resistance Tester, also known as a megohmmeter. Composed of medium to large scale integrated circuits, the UT515A digital megohmmeter has a high output power and 6 voltage range (250V/500V/1000V/2500V/5000V/10KV). The rated insulation test voltage：250V-10KV, and the insulation resistance measurement ：0.01M Ω -1000G Ω DC voltage measurement ：0-1000V AC voltage measurement：0-750V.
• 【High cost-effectiveness】The UT515A 10KV digital megohmmeter is at the same level as international brand competitors in key hard indicators such as test voltage (10kV), measurement range (T Ω level), short-circuit current (5mA)And has a large LCD screen backlit display, which can ensure the efficiency of users working in dark places.fully meeting the vast majority of on-site testing needs.
• 【Short circuit current test】UT515A mega tester can test short-circuit current 5mA, which is a very critical performance indicator. A larger short-circuit current can charge capacitive loads (such as long cables) faster, shorten testing time, and more effectively penetrate weak leakage on the surface of insulators, making measurement results more accurate and stable.
• 【data storage】It has the function of 500 sets of data storage, and can be connected to the host computer through USB. Data review, alarm, automatic shutdown and other functions.
• 【Application 】UT515A 10kV megohmmeter is widely used for preventive maintenance and troubleshooting of high-voltage electrical equipment. include testing insulation in power transformers, generators, and motors in utility and industrial plants. It is essential for verifying the integrity of high-voltage power cables, switchgear, and busbars. The tester also performs Polarization Index (PI) and Dielectric Absorption Ratio (DAR) tests to assess insulation health on industrial machinery, AC/DC drives, and backup systems. used for commissioning new installations and ensuring safety compliance in telecommunications, commercial buildings, and various industrial electrical systems.
