Automatic High Voltage Tester

Product Description

An Automatic High Voltage Tester (AHVT) is a device used to test electrical insulation of various types of equipment, such as transformers, cables, motors, and generators. The AHVT applies a high voltage to the equipment and measures the resulting leakage current, which indicates the condition of the insulation. The AHVT is designed to ensure that the equipment is capable of withstanding the specified voltage without breakdown or damage to the insulation.AHVT typically consists of a high voltage power supply, a voltage divider, a measurement circuit, and a control system. The power supply generates the high voltage, which is divided down by the voltage divider to a level that can be measured by the measurement circuit. The measurement circuit typically includes a current sensor and a voltage sensor that measures the leakage current and the applied voltage, respectively.
