Product Description:
The VICTOR 4700 wireless PT secondary voltage drop load tester is used to measure the secondary voltage drop as well as the voltage, phase and other parameters of the voltage transformer wirelessly. The instrument consists of two handheld measuring terminals, and the single device can be used as a three-phase phase voltammeter and a secondary load tester. Through wireless connection, the two machines can be used as a wireless secondary voltage drop load tester to realize synchronous measurement of voltage and phase between different positions in the substation, and measurement of secondary line voltage drop and error on the PT side. The instrument adopts a special measuring chip, with very high precision electrical parameter measurement, can disy the change of parameters to be measured in real time, and has the function of one-key data saving
Application field:
Is the power system electric energy metering and relay protection professional secondary circuit field detection of a new generation of instruments, also widely used in electrical equipment manufacturing, petrochemical, iron and steel metallurgy, railway electrification, scientific research and teaching departments
Product Features:
1. Use 5 "touch color screen, Chinese interface, easy and fast operation, accurate and reliable;
2. Using large capacity rechargeable lithium battery, with data storage, data access, automatic shutdown,USB data upload and export functions;
3. Measurement personnel only need to connect the operation, the instrument will automatically measure, real-time update data, convenient for field analysis;
4. Adopt complete isolation technology to avoid the occurrence of safety accidents;
5. GPS synchronization technology is adopted to ensure the accuracy of the synchronous measurement of the secondary pressure drop. The pressure drop can be measured without GPS, but the phase, ratio and phase difference will not be disyed
