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.

来自Sifam Tinsley的ND10是一种数字式可编程面板仪表，用于测量平衡和不平衡系统中的三相、四线电网参数。它也能显示测量的数量和它们同时的数字传输。该仪表还能控制和优化电力电子设备、系统和工业装置。该仪表可用于测量电压和电流的有效值;有功、无功和表观功率;有功、无功、功率参数;频率，15-，30- 60分钟平均有效功率和THD。另外，中性线的电流是由相电流矢量计算的。电压和电流的值乘以给定的电压和测量变压器的电流比。电力和能源指标考虑到所有程序的比率值。所有测量值都可以通过RS-485接口发送给主。当选定的参数超出设，继电器输出信号报警。脉冲输出可用于三相真能的消费检查。该仪表也能够检测和信号不正确的相序。ND10仪表内部由测量电路供电。
