ETCR4500 Wireless PT Secondary Voltage-drop/Load Tester used for wireless synchronous measurement of secondary voltage drop, load, current, voltage, phase and other parameters of the potencial transformer in substation.  Adopt 5 inch touch color screen, easy and convenient operation, large capacity lithium battery, USB interface. The single tester can be used as three-phase voltammeter, load tester and three-phase unbalance degree tester. For two testers can be used as wireless phase voltammeter, can test the phase relationship between current, voltage, current & voltage in substation different positions.can wireless synchro testing the line voltage-drop of PT side, and can measure the line voltage-drop of single phase or three phase.The instrument adopts GPS and LORA synchronous technology to ensure the accuracy of synchronous measurement of secondary voltage-drop. The operation personnel only need to wiring operation, the instrument will automatically measure, and update data in real-time, which is facilitate the field analysis.
