Product Description
The system is specially designed for PDfree AC withstand voltage test for electric generator, capacitance of single phase to ground is 0.4-1.2uF, test voltage is no more than 24kV.
Features
1.Countering over-voltage and transferring over voltage protection: the device with proper connection mode,
perfect protection link and energy absorption step by step, prevent countering over voltage and transferring over-
voltage damage.
After years of on-site practice proved that, when the tested objects was flash over or breakdown, can avoid the
complete testing equipment and testing from violations and threats of over-voltage. At the same time also
can avoid the fault point of tested objects do not expand injury after flash over or breakdown.

2. Small volume, light weight, easy to install and transfer, simple wiring, very suitable for field use by personnel operation.
3. Main functions of inductance adjustment resonant test device:
-
(a) The direct reading function for reactor core clearance:
-
This device installed clearance observation hole in the reactor, can be directly read out the iron core clearance, to guide the operation, also installed the clearance limit switch and indication.
-
(b) Automatic step-down function when arrived at withstand voltage time:
-
Withstand voltage timing adopts digital display timer. And when it arrives at withstand voltage time, the system will automatically step-down.
-
(c) Zero closing operation, zero boosting function:
-
With zero limit function, if the regulator is not at zero, the high-voltage output button can not close, ensure the system to boost from zero.
-
(d) Over-current protection function:
-
The system is equipped with a electromagnetic over-current relay, the relay has strong anti-interference ability, quick action, avoid the test objects do not damaged by over-current.
-
(e) Over-voltage and test object flashover protection function:
-
This device is equipped with electronic over-voltage flashover protection board,
-
avoid the test objects do not damaged by over-voltage and flashover, and with
-
rapid action.
-
(f) The real-time monitoring function of the test data:
-
Enable to monitor the voltage and current of high voltage side and low voltage side, can be more intuitive understanding of the test situation.
