The EPCL Transmission Line Test System is a kind of high-precision testing equipment for testing all kinds of high-voltage transmission line parameters in the field or laboratory of power station, substation, etc. The instrument is an integrated structure with built-in variable frequency power module and variable frequency and adjustable voltage output power supply. The frequency can be changed to 45Hz or 55Hz. The digital filter technology is used to avoid the interference of power frequency electric field to the test, which fundamentally solves the problem of accurate measurement under the interference of strong electric field. At the same time, it is suitable for the situation that the generator is used for power supply detection after power failure.
Features:
♦ Integrated structure, small volume and light weight.
The internal integration of the instrument provides a simple and convenient test method for the test.
♦ The power supply is simple and convenient.
All the measuring processes of the instrument only need to be connected to the mains voltage of 220V, which can solve the problem of inconvenient connection of 380V in the existing measuring methods.
♦ Strong anti-induction voltage ability.
The anti-induction voltage circuit is used inside the instrument to ensure that the instrument can withstand higher induction voltage (the anti-induction current can reach 80A), and can work normally under the high induction voltage of 30000 volts.
