GF311 10A clamp Handheld Multifunction phase angle meter for Protection Relay Test

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.

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 20 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.

FEATURES

Simultaneously measuring three-phase voltages, current, power, frequency, power factor, phase, etc.
Display vector map for the use of user directly.
Horizontal liquid crystal big screen TFT displays all electric parameters;
The smallest current it can measure is 1 mA, 2 mA above can display vector diagram;
Small volume, light weight and the operation is simple, convenient;
DSP digital signal processing chip, wide measuring range, high accuracy, good stability;
It can store data; data can be using computer software to upload for management;
Range switches automatically, software for be calibrated.
