Substation Equipment: Meters

Meters
Various types of meters are found in substation control houses. They all are measuring devices and can be an indicating meter or a recording meter. An indicating meter shows on a dial the quantity being measured. A recording meter makes a permanent record of the quantity being measured, usually by tracing a line on a chart or graph. Newer recording meters store the information electronically. The photo below left is an indicating amperage meter. On the right is a recording meter.
