Multifunction Three-Phase Phase Voltammeter can measure the voltage amplitude, current amplitude, voltage phase, current phase, the phase between voltage and current, frequency, power, active power, reactive power,harmonic and so on parameters at the same time. 1. Model No.: ETCR4400 2. Current Range: 0.001A-20A 3. Voltage Range: 2V-700V 4. Phase Range: 0°~360° 5. Harmonic range: 2 ~ 21 times 6. Power Supply : DC7.4V, 5200mAH rechargeable lithium battery

Used for wireless synchronous measurement of voltage amplitude, current amplitude, voltage phase, current phase, frequency, power and other parameters of different measurement points in the secondary circuit of the substation, and can also synchronous display the three-phase voltage and current vector diagram in the master and slave machine screen. Solve the problem that current and voltage cannot be measured at different points in smart substation completely. 1. Model No.: ETCR4480 2. Voltage Range : 2V~700V 3.
