GF311 Handheld Multifunction Protection Relay Test, phase angle meter for measuring 0° to 360°
The GF311 is specifically designed for measurements on electrical power systems. It is capable of displaying the phase angle relationship between three power signals, which can be three currents, three voltages or any combination. Currents up to 10 A and voltages up to 500 V can be applied directly to the instrument. The current input range can be extended by new clamp on cts.
GF311 Phase-Angle Meter an instrument used to measure the cosine of
the phase-shift angle, or the power factor, between voltage and
current in electric AC circuits at frequencies specified for mains
used by industry or to measure the phase difference of electric
oscillations.
GF311 multifunction phase angle meter can be applied to electric power dispatching center, relay protection department or relay protection in power plant. Its metric division class makes it suitable for petroleum, railways and the iron and steel industries also. it can be suitable for checking polyphase metering installations, testing protective relays, make comparative test in electrical substations, and verifying the phase angle deviation on power transformers.
