In Figure 7.16 is shown the construction of three-phase kWh-meter and wiring.<\/span> KWh-meter three-phase having ten terminals.<\/span> Torque moving the disk rotational torque is the sum of each phase.<\/span> Furthermore, the swivel moving mechanical disc recorder, and calibrated to show the total energy used by a network of three-phase systems.<\/span> For the purposes of determining the energy consumption that has been used by the user, the kWh-meter differentiated tariffs Single and Dual tariff kWh-meter.<\/span><\/p>\n kWh-meter Dual rates are used to measure energy (KAH) during peak load time (PLT) and during the time in-Outer Peak Load (OPLT).<\/span> kWh-meter double tariff has two scale readings are for PLT and OPLT.<\/span> To set this load time to use a time switch (relay time).<\/span> For the measurement of energy consumption (kWh) in three-phase systems, can be reached in two ways:<\/span> Here is an example of a nameplate on a three-phase kWh meter, double fare, made in Indonesia.<\/span>
