Đồng hồ Ampe kìm đo dòng điện rò BENNING CM 9
Error-related leakage currents are caused by weak insulation or insulation damages. The BENNING CM 9 allows quick and precise localization of all error types. By means of preventive measurements, possible damages due to uncontrolled leakage currents can be avoided in advance.
- the device is constructed and tested in accordance with DIN VDE 0411 Part 1 / EN 61010-1, DIN VDE 0404-4
- measurement of leakage currents and differential currents in electrical systems (VDE 0100) and devices (VDE 0701-0702, BetrSichV ( = German Health and Safety at Work Regulations))
- highest resolution of 1 μA in the 6 mA measuring range
- reliable and easy detection of insulation faults (e.g. defective cables, loose terminals, contamination, moisture)
- measurement without switch-off during normal operation of the system / device
- ideal for preventive maintenance and fault localization (protection against damages and personal injury, blackouts etc.)
- precise and reproducible measuring results up to 100 A
- optimum screening against external magnetic fields
- compare function signalises exceeds the respective threshold (0,25 mA, 0,5 mA, 3,5 mA)
