Typical Applications |
| The MT100-WAx series measures active power in single, 3 phase 3 or 4 wire balanced and unbalanced systems. Using the time division multiplier circuit means that they can be used over a wide range of input waveshapes. The D.C. Output signal is directly proportional to the instantaneous real power. Typical applications include the measurement of power in switchboards, power stations, generating sets. |
