In their daily work, power workers often need to test the insulation resistance value of high-voltage power equipment, which requires the use of an insulation resistance tester. So specifically, why is this equipment so popular among power workers?
1. Adopts microcomputer control, menu operation, large-screen LCD dot-matrix display, stable performance, and is an intelligent instrument.
2. Strong anti-interference capability, suitable for measurement in strong electromagnetic interference environments.
3. Has 8 voltage output ranges: 50V, 100V, 250V, 500V, 1.0kV, 2.5kV, 5.0kV, and 10.0kV.
4. The high voltage of each range can be continuously adjusted from zero.
5. Automatically measures R15, R60, R600, and automatically calculates absorption ratio and polarization index.
6. Strong load capacity, short-circuit current about 5mA.
7. Maximum measurement range is 0 to 10TΩ, with automatic range switching.
8. Combines analog bar pointer and digital display to vividly show data trends and accurate measurement results.
9. Displays test time at all times, and the buzzer automatically sounds every 15 seconds as a reminder.
10. Automatically discharges high voltage after measurement, with discharge time not exceeding 30 seconds.
11. Automatically measures ambient temperature, air humidity, and the date and time of each test.
12. Can save 60 sets of measurement results, and data can be retained for 20 years without loss.
13. Comes with an RS232 serial interface for data communication with a computer.
14. If there is no operation for 5 minutes, the system automatically beeps to prompt shutdown.
15. Has comprehensive and complete protection functions, with high working reliability.
The insulation resistance tester is a very conventional high-voltage power test equipment, and power workers need to be proficient in the principles and characteristics of this equipment.
