In a watt-hour meter, how is the "potential coil" connected to the line?

The potential coil of a watt-hour meter is connected in parallel with the load it's measuring. This connection allows the potential coil to measure the voltage across the load accurately, regardless of the current flowing through the load.

In a watt-hour meter, the potential coil is essential for determining the amount of work done in an electrical circuit, as it takes the voltage into account. By connecting it in parallel, the meter can gauge the actual voltage being supplied, which is crucial for calculating energy consumption in watt-hours.

Understanding this configuration is vital for linemen and apprentices, as it directly relates to how energy meters function in residential and industrial applications. It helps ensure that accurate readings are taken, which is key for billing and energy management.
