Short-circuit currents in three-phase a.c. systems - Part 0: Calculation of currents
Applicable to the calculation of short-circuit currents:
- in low-voltage three-phase a.c. systems
- in high-voltage three-phase a.c. systems
operating at a nominal frequency of 50 Hz or 60 Hz.
Systems at highest voltages of 550 kV and above with long transmission lines need special consideration.

Natural gas — Determination of potential hydrocarbon liquid content — Gravimetric methods
This International Standard describes the principles of, and general requirements for, two gravimetric methods for
the determination of the potential hydrocarbon liquid content of natural gas, or similar gas, at a given pressure and
temperature. Two methods are specified in this International Standard to determine the amount of condensate in a
sample gas:
_ Method A: a manual weighing method;
_…
