GF311 phasor meter is one ideal tool of checking phasor on site, check power system three phase voltage phase sequence(U1 U2 U3), display phase shift diagram, it can measure voltage,current, power, frequency, harmonics etc. Suite for 3 phase 4 wire, 3 phase 3 wire, 1 phase 2 wire and 1 phase 3 wire. This model phase angle meter is the best power engineering commission device for substation. It can be applied to electric power dispatching center, relay protection department or relay protection in power plant. Its electric accuracy class makes it suitable for petroleum, railways and the iron and steel industries also.
