Trivector Meter
A trivector meter is designed to record active, reactive and apparent energy along with MD indicators on all. The trivector meter is a compact unit. It exchanges the set of instruments that must otherwise be installed and has the benefits of yielding full and more accurate data. The trivector meter consists of three various recording elements, namely, kWh, kVAh and kVARh. The recording principle of kWh and kVARh element is the similar as elaborates in 3-phase meters whereas kVAh element records mechanically along with the differential gearing arrangement. The meter is extremely reliable, robust and practically free of any adjustment even for a long period of service. If the P.F. of the installation is leading, then kVARh element of the trivector has a tendency to record in reverse direction. But this is checked through providing a back stopper within kVARh element and if the power factor is leading, it records at unity power factor.
List four sources of information which are essential to the designer of this electrical installation.
Testing of CT Operated Meters The subsequent tests should be carried out for CT operated meters: i) Ratio test through primary injection kit, ii) Polarity test, iii)
