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.
