KDDQ2678A Insulation Resistance Tester for Water Cooled Generator

KDDQ2678AInsulation resistance test of water-cooled generatorceremony

KDDQ-2678 series water-cooled generator insulation resistance tester

Used to measure the insulation resistance, absorption ratio, and chemical index of stator windings in water-cooled generators. Large output capacity, capable of effective testing in complex environments with low water resistance, and able to overcome the impact of various on-site interferences on testing.

Product Features
ProductFeatures
The range can reach 100GQ, up to 1MQ;
The output power can reach 500W, the current can reach 100mA, and when the drop resistance of the winding to the water collection pipe is as low as 2500V/25kQ or 5000V/50kQ, the port voltage drop is less than 10%;
The resistance between the water collection pipe and the machine base is as small as 3kQ, which can still ensure measurement accuracy;
Automatically compensate for comprehensive interference after startup, using current measurement device technology based on equipotential high current shielding to effectively compensate for various chemical potentials and ensure the authenticity of measurement values
Using a 7-inch touch color screen, real-time display of various parameters on the same screen: port voltage: water branch resistance, Rt，R15S，R60S，R10min， Absorption ratio and chemical index accurately reflect on-site working conditions;
During testing, the insulation resistance value is displayed in real-time using both digital and virtual pointer display methods. The virtual pointer uses logarithmic scale counting, with small fluctuations in the displayed value, providing a visual display of the testing process of the capacitive test sample. The digital display of the measured value is convenient for reading;
Text prompts for operation steps and testing status can diagnose and analyze the testing status, provide operational instructions, and improve testing efficiency;
Overload protection function, when the water resistance is very low or even short circuited, the instrument automatically shuts off the high voltage without damaging the instrument;
Can store test data and upload it to a computer via USB.
