Combined line and phase voltmeter selector

What it represents

This representation identifies a selector covering phase-to-phase and phase-to-neutral voltage measurements. One selector covers both line-to-line and line-to-neutral measurements. The measurement function changes with position even though the meter and its physical terminals remain the same.

List the selected conductor pair or phase/reference path for every position. Use the selected switch’s contact programme instead of inferring connections from the face labels alone.

How to read it

• Provide a position table specifying each measurement path.
• The symbol cannot replace the actual switch contact programme.

Information to show or reference

• Identify the associated device, circuit or diagram boundary.
• Provide a position table specifying each measurement path.
• Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
