The KDZD2030 is a portable, handheld multifunctional three-phase phase volt-ammeter combining phase and harmonic test functions. It features a 3.2-inch color TFT display and intuitive operation, supporting measurement of AC voltage (30~450V), current (10A~1500A), phase (-180°~+180°), and power parameters. With built-in 32MB storage (30,000+ records) and USB export, it enables efficient analysis of transformer wiring, phase sequence, and relay protection systems. Its lightweight design and long-lasting lithium battery make it ideal for field use.
