Many machine and system operators know this: The combination of an AC\/DC sensitive residual current circuit breaker (RCCB) – increasingly used in industry – and modern automation technology has its pitfalls. Components such as frequency inverters and RFI filters can generate high leakage currents, which are incorrectly recognized as residual currents by an upstream RCD and thus lead to disconnection. This results in losses due to downtimes.<\/p>\n\n\n\n

Although the level of leakage current load can also be measured using other methods, these lack a detailed analysis of the frequency components, which is essential for a correct assessment of the situation.<\/p>\n\n\n\n

The LEAKWATCH measuring and analysis system was developed specifically for this purpose.<\/strong> It measures the leakage current load and displays the frequency ranges in high resolution. The option of displaying the tripping characteristics of all common RCDs enables a detailed analysis of the situation and the countermeasures suggested by the software make the selection of suitable filter measures child’s play!<\/p>\n\n\n\n

In short:<\/strong> LEAKWATCH is the tool<\/strong> for effective analysis and optimization of leakage currents!<\/p>\n<\/div>\n<\/div>\n\n\n\n
