Subject:
Capacitance
Key words:
- Capacitance
- Charge
Decision taken by
ETF3 and confirmed
by CTL at its 38th
meeting, in Toronto
Question:
How can the stored charge be measured, in particular where the circuit is complex?
Decision and Explanation:
Only the charge accessible to the user is of concern under the standard. Therefore, where the
circuit is complex, it is considered that a method of measurement from the accessible part is
needed. It is, therefore, recommended that a procedure of discharge through a defined
resistor is used, monitoring the voltage – time profile to provide a method of calculation of
charge.
When this method is used it is requested that details are recorded in the report for the benefit
of CB members.
The method described in IEC 60950 Subclause 2.1.10 is recommended.
