66 / 120 page  ADE7978/ADE7933/ADE7932 Data Sheet Rev. 0 | Page 66 of 120 TOTAL HARMONIC DISTORTION CALCULATION The ADE7978 computes the total harmonic distortion (THD) on all phase currents and voltages. The THD expressions are shown in the following equations: 1 2 1 2 I I I THDI − = (49) 1 2 1 2 V V V THDV − = where: I and V are the rms values of the phase currents and voltages stored in the AIRMS, AVRMS, BIRMS, BVRMS, CIRMS, and CVRMS registers. I1 and V1 are the fundamental rms values stored in the AFIRMS, AFVRMS, BFIRMS, BFVRMS, CFIRMS, and CFVRMS registers. The THD calculations are stored in the AVTHD, AITHD, BVTHD, BITHD, CVTHD, and CITHD registers (Address 0xE521 to Address 0xE526). These registers are 24-bit registers in 3.21 signed format. This means the ratios are limited to +3.9999 and all greater results are clamped to it. Like the xIRMS and xFIRMS registers, the 24-bit signed xITHD and xVTHD registers are transmitted as 32-bit registers with the eight MSBs padded with 0s (see Figure 67). |
