5.1.2.1.- WIRING: Circuit type
Choose the circuit type to be analysed (rotary input).
− 3Φ4 Wires: To measure Three-phase systems with Neutral wire.
− 3Φ3 Wires: To measure Three-phase systems with Neutral wire. For this
arrangement 3 current clamps must be used.
− 1Φ: To measure Single-phase systems.
5.1.2.2.- PT/CT : Transformation ratios
Voltage and current transformation ratios setting. The program will
sequentially inquire for following data:
− PRIM. V: Voltage transformer primary value.
− SEC. V: Voltage transformer secondary value.
− PRIM. I: Current transformer primary / Current clamp primary, used for
measuring the line currents.
NOTE 1 : If voltage is directly measured (no voltage transformer is used), you
must set PRIM.V = 1/SECV.V = 1.
NOTE 2 : PRIM. I --> This option permits to program:
a) The ratio of the Current clamp to be used.
b) In case of a high voltage system, the measurement will be carried out through the
secondary of current transformers. A shunt ATS-III 5 A a.c./ 2 V a.c. or CP5 clamp will
be then required to enter the measurement signal into the AR5-L analyzer (Never
directly connect the 5 A signal to the AR5-L.). For this case, the C.T. primary must be
set at the primary value of the C.T. used for measuring purposes.
Ratio set must be modified for each Current or transformer type change to avoid
measurement mistakes. Standard clamps give a voltage output (generally 2 a.c. at full-
scale).
NOTE : Secondary is always set at 2 V a.c. (it is not user-programmable).
