INSULATION TEST METHOD FOR EXPLOSIVE CIRCUITS Russian patent published in 1994 - IPC

Abstract RU 2022289 C1

FIELD: electric measurement technology. SUBSTANCE: test voltage is applied through auxiliary circuit between leads of short-circuited explosive circuit and ground; auxiliary circuit is series LC circuit where capacitor is inherent capacitance of measurement instrument increased by metal strip. LC circuit is resonance-tuned to frequency of test voltage source. Test voltage current and frequency are selected from relations given in invention description. EFFECT: improved safety in tests. 3 cl, 1 dwg
