AL606 Water cooled generator insulation tester
Performance standards:
Q/HTDL203-2004
Features:
1, test voltage is negative pressure 2.5kV, with load capacity.
2, can automatically compensate and eliminating polarization potential influence on the test result of the cooling water. Meeting resistance as low as between pipes and motor 3k when ω, has been able to ensure measurement accuracy.
3 R15, R60, R600, automatic measurement, automatic calculation of absorption, polarisation index.
4, measuring range 0~10G w, automatic switching range.
5, micro-computer control, menu operations, large-screen liquid crystal display, method of low-voltage shielded measurements, performance and stability.
6. combined, analog pointer and digital display, images indicate that changes in data trends and accurately measure the results.
7, test time are displayed at any time, and automatically every 15 seconds buzzer beep prompt.
8, measurement is completed automatically discharge high pressure, high pressure discharge time of not more than 5 seconds.
