Meter Data
The meter data differs significantly between relays. Therefore, the data stored in a specific register
depends on the data available from the attached relay. All meter data is primary quantities, unless
otherwise indicated. Table 4.8 lists the possible quantities for each register.
Some quantities have the whole and fractional parts separated into two registers. In these cases,
the second register contains the fractional part multiplied by 10000. For example, a power of
73.1274 MW would be reported as 73 in register 44 and 1274 in register 45. Similarly, a reactive
power of -8.2390 MVAR would be reported as -8 in register 46 and -2390 in register 47.
For this data to be available, the SEL-2030 must be set to perform 20METER collection with the
attached relay.
