Inverters used in rail and power system applications convert high-voltage power. To measure the efficiency of such conversions, it’s necessary to measure voltages of 1000 V and above. The VT1005 divides voltages of up to 5000 V and outputs them to a power analyzer. In order to measure the efficiency of high-efficiency inverters with a high degree of precision, you need to be able to accurately measure power from DC to high frequencies. Thanks to its excellent frequency flatness, the VT1005 makes accurate measurements at frequencies ranging from the fundamental wave to switching-frequency components. HIOKI AC, DC HIGH VOLTAGE DIVIDER VT1005 Price in Bangladesh reflects its premium precision for voltage measurement up to 5kV. Ideal for R&D and production lines, this device ensures accurate testing in high-voltage environments. VT1005 offers superior safety, making it a reliable choice for professionals across the electrical and electronics industries.
