KDDQ-2678 Insulation Resistance Tester for Internal Water Cooling Generator

　　It is used to measure the insulation resistance, absorption ratio and polarization index of stator windings of water-cooled generators. The output capacity is large, it can be tested effectively in the complex scene and the water resistance is low, and can overcome the influence of various interferences on the test scene.

　　Features

• 　　The range can be as high as 100GΩ and as low as 1MΩ;
• 　　The output power is up to 500W, the current is up to 100mA, and the drop resistance of the winding to the water collection pipe is as low as 2500V/25kΩ or 5000V/50kΩ, the port voltage drops <10%;
• 　　The resistance between the water collection pipe and the base is as small as 3kΩ, and the measurement accuracy can still be guaranteed;
• 　　Automatically compensate for the integrated interference after booting, using the patented technology of the current measuring device based on the equipotential large current shielding to effectively compensate various polarization potentials to ensure the authenticity of the measured values;
• 　　Using a 7-inch touch color screen, the same screen can display various parameters in real time: port voltage, water branch resistance, Rt, R15s, R60s, R10min, absorption ratio and polarization index, etc., which accurately reflect the on-site working conditions;
• 　　During the test, the insulation resistance value is displayed simultaneously in real time with two display modes, digital and virtual pointer. The virtual pointer adopts logarithmic scale counting, the display value is small, and the test process of the capacitive sample is displayed intuitively. The digital display measurement value is convenient for reading;
• 　　The text prompts the operation steps and test status, which can diagnose and analyze the test status and indicate the operation to improve the test efficiency;
• 　　Overload protection function, when the water resistance is very low or even short circuit, the meter will automatically turn off the high voltage to ensure that the meter is not damaged;
• 　　Test data can be stored and uploaded to the computer via USB.
