GAS SENSOR - Patent - Europe PMCeuropepmc.org/patents/PAT/WO0043765A gas sensor for the detection of gases comprises a housing and an active element disposed within the housing. The active element is surrounded by a porous insulating material having a bulk density no greater than 0.15 g/cc.
Leak detection - CERN· PDF fileare used at the insulating vacuum tank resu lting in a total permeation rate of 2 · 10 5 mbar l/s/m . This long list shows that during design and manufacture great care is necessary to avoid potential leaks. 4 Leak detection methods The aims of a leak search are to localize a leak and/or to determine the total or local leak rate.
Guidelines for transformer application designs. | EC&M manufacturers, in order to meet demands for good regulation, design transformers with leakage reactance as low as 2%. A transformer so designed is liable to be severely damaged if a short circuit occurs on the transformer's secondary, especially if the total power on the system is large (a stiff source with low impedance).
