Three Phase Multifunction Digital Phase Angle Meter High Accuracy Electronic Testing Equipment
GF311 Portable Electronic Testing Equipment of Three Phase multifunction digital phase angle Meter with accuracy 0.1°
(Accuracy 0.5%)
Application
It 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.
GF311 multifunction phase angle meter is suited for checking polyphase metering installations, testing protective relays, make comparative test in electrical substations, and verifying the phase angle deviation on power transformers
Direct digital reading to tenths of a degree (0.1°) – does not require calculation or interpretation. Designed for use in substation or industrial environments – transport case provided for rugged protection. Phase angle calculated from of any combination of two power signals to be measured giving broad application capability. Timer with high accuracy for contact or voltage trig. Local calibration.
Main Functions and Features
1. Simultaneously measuring three-phase voltages, current, power, frequency, power factor, phase, etc.
2. Display vector map for the use of user directly.
3. Horizontal liquid crystal big screen TFT displays all electric parameters;
4. The smallest current it can measure is 1 mA, 2 mA above can display vector diagram;
