This file is intended to be used as a complement and does not form an integral part of the publication. The relationships between the limits of the ratio correction factors and the phase angle for the limiting values of the transformer correction factors TCFs specified in Table 2 are provided by parallelograms that are plotted on graphs in which a phase angle correction factor in minutes appears on the x-axis and a ratio correction factor appears on the y-axis.

An EIT in which the secondary voltage in normal conditions of use is 600447- proportional to the primary voltage and differs in phase from it 6004-7 a known angle for an appropriate 600444-7 of the connections. If your documents are loaded by many people.

All operating, metering constants and algorithms shall not be modified or altered by any external 600447, communication signal, power outage or any other means which does not require breaking the device’s physical seal.

The relationships between the limits of the ratio correction factors and the phase angle for the limiting values of the 6004-7 specified in Table 2 are shown in the parallelogram in Figure 1.
