HY2450 water-cooled insulation resistance tester

HY2450 water-cooled insulation resistance tester

Used for measuring and testing water-cooled generators, as well as conducting insulation tests in the laboratory or on-site, it includes a high-precision microcurrent measurement system and a digital boost system. Simply connect the test sample with a high-voltage wire and a signal wire to measure. The measurement is performed automatically, and the results are displayed on a large LCD screen and stored.

1、 Main features

1. It is controlled by a 32-bit microcontroller with a fully Chinese operating interface, making it easy to operate.

2. High output current (greater than 25mA at 2500V), short-circuit current ≥ 25mA.

3. The high-voltage generation module adopts fully enclosed technology with protective resistors inside, ensuring safety and reliability.

4. Anti rodDisturbance energyStrong capability, able to meet the on-site operation of ultra-high voltage substations.

5. Automatic discharge after testing and real-time monitoring of the discharge process.

6. Suitable for measuring insulation resistance, absorption ratio (R60S/R15S), and polarization index (R10min/R1min) of water-cooled generators.

7. Test high voltage at 2500V/5000V.

8. Automatically compensate and adjust the polarization potential of water. The resistance between the machine base and the water collection pipe can be as low as 10k Ω to ensure measurement accuracy.

9. High output power, the load resistance between the line and the water collection pipe can be as low as 100k Ω (2500V)/150k Ω (5000V), and the insulation resistance measurement can be as low as 1M Ω (2500V)/2M Ω (5000V).

10. The insulation resistance value is indicated by a simulated progress bar, which can visually observe the testing process of the capacitive test sample without delay. Logarithmic scale, small indication fluctuation, convenient reading.

11. The digital display adopts a 3 1/2 LCD digital meter.

The LCD timer displays the test time and repeats the cycle from 0 to 32 minutes to show its minutes and seconds. The bee beeps every 15 seconds.

13. It can automatically measure and memorize R15S, R60S, R10min, absorption ratio, and polarization index for review and reading upon completion of the test.

14. It has the function of automatically compensating and adjusting the polarization potential of water.
