Hi, It is difficult to determine the exact voltage on each piece of the electricity network without going to inspect each individual device on site (potentially difficult, unsafe, potentially illegal), although there are some visual clues in the overhead photos (size of substation, power route, size & type of pole, etc.). There are hundreds of thousands of transformers and twice as much power line as there is public roads.
voltage=low, voltage:primary=low, voltage:secondary=low, etc. are placeholder values I created to help identify the voltages used on the power network. 1. voltage=* can apply to any part of any electrical device. 2. voltage:primary=* primarily applies to transformers and substations and is the voltage for the side the power is coming from. 3. voltage:secondary=* primarily applies to transformers and substations and is the voltage for the side the power is going to. 4. There are also voltage:tertiary=* and voltage:quaternary=* for locations with multiple voltages. These are the values I have been using: 1. High = I presume the voltage to be 110,000 volts or higher but can't say which. 2. Medium = I presume the voltage to be 38,000 volts but can't say for definite. 3. Low = I presume the voltage to be 20,000 volts or lower but can't say which. The network operators and voltages used across Ireland are below. Could I ask where the error is showing? The usual debugging sites normally associate errors with the most recent contributor - usually me.
