ND10 from Sifam Tinsley is a digital programmable panel meter destined for the measurement of the 3-phase, 4-wire power network parameters in balanced and unbalanced systems. It is also capable of displaying measured quantities and their simultaneous digital transmission. The meter is also capable of controlling and optimization of the power electronic devices, systems, and industrial installations. The meter can be used for measuring: RMS value of voltage and current; active, reactive and apparent power; active and reactive energy, power parameters; frequency, 15-, 30- and 60-minute mean active power and THD. Additionally, a current in the neutral wire is calculated from the phase current vectors . Voltage and current values are multiplied by given voltage and current ratios of measuring transformers. Power and energy indications take into account all programmed ratio values. Any and all measured values can be sent to the master via the RS-485 interface. The relay outputs signal alarm when selected parameters exceed set limits. Impulse output can be used for consumption check of the 3-phase real energy. This meter is also able to detect and signal incorrect phase sequence. The ND10 meter is powered internally by the measuring circuit.
