Power line filters safeguard EMC test chambers

In most situations nowadays, systems must be available 24 hours a day, seven days a week, and operate safely and securely without any interruption in service due to interference. That is no more so than in the universe of EMC test chambers. Such specialised chambers test electronic devices against regulatory standards applicable to both radiated and conducted radio-frequency (RF) emissions and immunity. MPE discusses.

Pulse current injection compliance at first time of asking

The well-established procedure for checking compliance of a HEMP filter with the Mil-Std-188-125 specification is to inject a very high current pulse into the front end of the filter and monitor the residual current flowing through. Such Pulse Current Injection (PCI) testing is conducted independently of the filter manufacturer, by trusted test houses utilising specialist and often proprietary equipment. No test house in Europe offers such commer...
