Product Description

SMG-2000 Dual-Clamp Digital Phase Voltmeter

 
Overview

The Dual-Clamp Digital Phase Voltmeter is a versatile field-testing instrument characterized by high precision, stability, low power consumption, and user-friendly operation. It enables direct measurement of AC voltage and current without breaking the circuit, as well as phase differences between two voltages, two currents, or voltage-current pairs. Additionally, it indirectly measures power factor and power, identifies three-phase sequence, determines transformer wiring groups, and distinguishes inductive/capacitive circuits. It is also applicable for testing secondary circuits and busbar protection systems, analyzing phase relationships among CT groups in differential protection, verifying wattmeter wiring correctness, and inspecting line equipment. Featuring an oversized LCD with 40mm-high digits and backlight, the display ensures clarity. It is widely used in power utilities, petrochemicals, metallurgy, railways, meteorology, industrial plants, research institutions, and metrology sectors.
