Take the smart route to manage medical device compliance. These provisional specifications are issued under the authority of section 12 of the Electricity and Gas Inspection Regulations. Electronic Voltage Transformers 4. If your documents are loaded by many people. 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.

The basic operating constant and the algorithm used in processing the measured quantities shall be stored within the EVT in such manner that they cannot be altered without breaking the device’s physical seal clause The terms “measuring voltage transformer” and “metering voltage transformer” are equivalent. Success is the ability to go from one failure to another with no loss of enthusiasm. The parallelograms defining the limiting values of the TCFs for voltage transformers are bound by vertices.
