the fundamental current of element j,

Ij(1)

No Yes

ΦUk−Ik1Phase difference between Uk(1) and

the fundamental current of element k,

Ik(1)

No Yes

1 i, j, and k are input element numbers. For example, when the number of input elements in wiring unit ΣA is

six and the wiring system of elements 1, 2, and 3 is three phase, four wire, i is 1, j is 2, and k is 3. ΦUi – Uj

represents ΦU1 – U2, the difference between the fundamental voltage signal of element 1, U1(1), and the

fundamental voltage signal of element 2, U2(1). In the same way ΦUi – Uk, ΦUi – Ii, ΦUj – Ij, and ΦUk−Ik

represent to ΦU1 – U3, ΦU1 – I1, ΦU2 – I2, and ΦU3 – I3, respectively.

2 Setting i to an input element, is the same as setting k to 1 in Φ(k).
