Profile

The KDZD series high-voltage phase comparator, developed by our factory with decades of experience in electrical safety instrumentation, addresses a critical yet hazardous task in power system operations: phase identification. Designed with operator safety and simplicity in mind, it features a robust analog pointer interface that clearly distinguishes between “in-phase” (near-zero indication) and “out-of-phase” (full-scale voltage reading). Available in multiple voltage ratings—from 380V up to 110kV—the KDZD combines portability, mechanical durability, and electrical reliability for daily use in demanding utility environments.

Features

✅ Metal-Film Resistor Voltage Reduction – ensures stable, linear signal attenuation with excellent long-term stability
✅ Analog Pointer Display – intuitive visual indication: “0” for in-phase, full scale for out-of-phase
✅ Multi-Functionality – supports phase comparison, live-line testing, and ground fault detection
✅ Lightweight & Portable – weighs only 1.4–3.2 kg depending on voltage class
✅ High Safety Standard – insulated rods tested well above operating voltage (e.g., 330kV for 110kV model)
✅ Wide Voltage Coverage – available for 380V, 3kV, 6kV, 10kV, 35kV, 66kV, and 110kV systems
✅ Field-Ready Design – telescopic insulating rod with ergonomic grip for easy handling at height
