Frequency Resonant System

Technical Features

1. The Frequency Resonant System unit possesses the overvoltage, overcurrent, zero start, system detuning (flashover) and other protective functions. The protective value of over voltage and over current can be adjusted as per requirements of customers. The protective function of flashover also can remember voltage value of flashover when there is a flashover of test object, which can be used for test analysis.

2. The weight of single piece of whole unit is very light with no more than 40kg, which can be convenient for field service.

3. There are three working modes for this unit, which is convenient for users to flexibly select according to field condition and improve the test speed.

Three working modes are fully automatic mode, manual mode and the mode with automatic tuning and manual boosting.

4. It can save data with data number of figure, which is convenient for users to identify and search.

5. The frequency starting poing can be set casually within specified scope and the frequency sweeping direction can be selected upward or downward during the automatic frequency sweeping process of the unit. Meanwhile, the large LCD screen can show scanning curve, which is convenient for users to intuitively understand whether they can find the resonance point or not.

6. It adopts DSP platform technology, which is convenient to add or delete functions and upgrade according to customers’ requirements, and enables the man-machine interface to become more humanized.
