Frequency conversion power supply and digital filtering suppress interference, ensuring reliable results in substations and environments with strong electromagnetic fields. High resolution and wide measurement range allow detection of dampness, aging, and local insulation defects, supporting routine checks, commissioning, and preventive maintenance across power systems and industrial facilities. Equipped with a large touch-screen interface, built-in memory, and real-time clock, the tester enables automatic storage, recall, and on-site printing via a micro thermal printer. Computer interface allows centralized management of results. Multiple protections, including grounding detection, overvoltage, overcurrent, and electric shock prevention, guarantee safe operation. Compact and portable, the HZ-2000H combines precision, efficiency, and safety, making it ideal for utilities, substations, research institutes, and field applications.
