The GF211D digital phase angle meter is engineered for safe, convenient, and high-reliability on-site phase measurement. Designed with dual voltage input terminals (U1, U2) and dual clamp current inputs (I1, I2), the instrument enables live-line testing without cable stripping or power shutdown, ensuring efficient and non-destructive field wiring.
It supports three mainstream wiring measurement modes: voltage-to-voltage phase testing, current-to-current phase testing, and voltage-to-current phase testing, covering most conventional power inspection scenarios. With clearly marked terminals, quick-connect cables, and non-contact current clamps, the device simplifies wiring procedures while lowering operational risks.
Integrated with automatic phase recognition, a high-definition LCD display, and reliable overload protection, the GF211D delivers stable and repeatable test data with minimal manual intervention. Even operators with limited experience can complete accurate phase detection effortlessly. Ideal for substation relay commissioning, transformer wiring verification, and industrial electrical maintenance, this phase angle meter serves as a practical and dependable tool for daily power field testing.
