peakstrøm
Peakstrøm is a term used in electrical engineering to describe the maximum instantaneous current drawn by an electrical circuit or device during operation. It is distinct from average or RMS current and is a critical parameter for assessing component stress, insulation, and protection strategies.
Origin and usage: The term combines 'peak' with 'strøm' (Norwegian/Danish for current), reflecting its prevalence in
Measurement and interpretation: Peak current is defined as the maximum value of i(t) over time. For a
Applications and significance: Peak current ratings are used in selecting fuses and circuit breakers, and in
Limitations and considerations: The peak value can vary with load, switching behavior, source impedance, and waveform
