40、bols, which are given as examples, each voltage circuit is represented by a line and each current circuit by a small circle. At the end of each line representing a voltage circuit, a circle(s) is (are) placed to represent (a) current circuit(s), arranged to have a point of common connection with tha

41、t voltage circuit. If a current circuit and a voltage circuit having such a common point of connection are not part of the same measuring element, the circle representing the current circuit is joined to the mid-point of the line representing the voltage circuit by means of a guideline not more than

42、 half the thickness of the first line. If a measuring element carries two current circuits whose number of turns are in the ratio 1/k, the diameters of the representative circles shall be in approximately the same ratio. The angle between two lines of a symbol represents the phase angle between the

43、corresponding voltages provided the positive direction be accepted as that going towards the common point in two-line symbols (for example, symbols 4.9 and 4.10), and in the trigonometrical direction in the case of triangular symbols (for example, symbol 4.8). In order to distinguish the direction o

44、f the voltage acting on each current, a current influenced by a positive direction of voltage shall be indicated by a black circle, and a current influenced by a negative direction of voltage shall be indicated by a white circle.
