AS 60038:2000 pdf – Standard voltages.
2.2 Lowest voltage of a system
The lowest value of voltage which occurs under normal operating conditions at any time and at any point on the system.
It excludes voltage transients, such as those due to system switching, and temporary voltage variations.
3 Supply terminals Point of supply
The point where the distribution system of the electricity supply authority and the electrical system of the consumer are connected.
4 Supply voltage
The phase-to-phase or phase-to-neutral voltage at the supply terminals point of supply.
5 Supply voltage range
The voltage range at the supply terminals point of supply.
6 Utilization voltage
The phase-to-phase or phase-to-neutral voltage at the outlets or at the terminals of equipment.
7 UtIlization voltage range
The voltage range at the outlets or at the terminals of equipment.
8 Rated voltage (of equipment)
The voltage assigned generally by a manufacturer, for a specified operating condition of a component. device or equipment.
9 Highest voltage for equipment
Highest voltage for which the equipment is specified regarding:
a) the insulation;
b) other characteristics which may be referred to this highest voltage in the relevant equipment recommendations.
The highest voltage for equipment is the maximum value of the “highest system voltage”
“highest voltage of the system” (see 2.1) for which the equipment may be used.
NOTES
1 The highest voltage for equipment is indicated for nominal system voltages higher than 1 000 V only. It is understood that, particularly for certain nominal system voltages, normal operation of equipment cannot be ensured up to this highest voltage for equipment, having regard to voltage-sensitive characteristics such as losses of capacitors, magnetizing current of transformers, etc.
In such cases, the relevant recommendations must specify the limit to which the normal operation of this equipment can be ensured.
2 It is understood that the equipment to be used in systems having nominal voltage not exceeding 1 000 V should be specified with reference to the nominal system voltage only, both for operation and for insulation.
3 Attention is drawn to the fact that in some equipment standards (for example. IEC 60335-I and IEC 6007 1-1) the term “voltage range” has a different meaning.
