معرفی محصول
With the continuous advancement and expansion of modern technology, higher demands are being placed on the reliability of power systems and high-voltage equipment. Accidents or damage to electrical equipment are often closely related to insulation defects. As electrical equipment tends to have larger capacity, higher voltage, diversified structures, and improved sealing, new and more stringent requirements have emerged for insulation testing. Under such circumstances, ordinary megohmmeters are no longer sufficient to detect the insulation performance of large-capacity equipment.
Power test procedures require a series of insulation performance tests for various power equipment, including cables, motors, generators, transformers, voltage transformers, high-voltage switches, and lightning arresters. The first and most fundamental test among these is the insulation resistance test.
When testing the insulation resistance of large-capacity power equipment, the measured resistance value is closely related to the pressurization time: the longer the pressurization time, the higher the insulation resistance value. This phenomenon is known as insulation absorption. To properly evaluate the insulation performance of the equipment under test, it is essential to first perform the absorption ratio and polarization index tests. These tests provide a critical safety foundation for subsequent insulation performance assessments, such as leakage current, dielectric loss, partial discharge, and other diagnostic tests.
In accordance with electric power standardization regulations, our company proudly introduces the BC2010 Insulation Resistance Tester. Featuring large capacity, high anti-interference capability, and stable performance, this tester is specifically designed to perform insulation resistance, absorption ratio, and polarization index tests on power equipment. It delivers accurate early-stage diagnostic information, providing essential support for the entire series of insulation tests.

Matters needing attention
1. Confirm the connection and correct and then start the test Note: the tested line ban mopping the floor, "high voltage output" light indicates have high voltage output, At this time strictly prohibited to touch the high-voltage wire! In the process of the test do not pull and plug tested line, so as not to endanger the personal safety and damage the instrument.
2. Battery measurement of instrument internal, Show dimor the boot does not show, undervoltage display light turn on,said battery is low, should promptly shut down the instrument and charging.
3. When the instrument is not used for a long time should be regularly to charge the battery (Two months for once). Frequently check whether the battery liquid leakage, Battery leakage will corrosion and damage the instrument .
4. Instrument stored in a dry, clean, no corrosive gas environment.
5. For large capacity load test, the tested finish have enough time discharge, the discharge is completed can disassemble test line. (Large capacitive load discharge is best for more than 1 minutes)
6. Instruments are not connected to the test product, Insulation resistance measured value is generally greater than T (1T=1000G), this value is generally random infinite values, like tested air, It is not practical.
7. If the instrument failure, Should be invited to professional repair personnel or send to the company repair, shall not be opened instrument, otherwise, the loss caused our company is not responsible for.
