ISKRA FQ 0307 Current Meter with Moving Iron

The FQ 0307 moving-iron instrument FQ 0307 is intended for installation in supervision panels of power distribution stations and transformer stations or wherever AC voltages and currents have to be measured in heavy-current installation. Its front frame is 72x72 mm. The incorporated moving-iron mechanism measures RMS values of AC currents in frequency range 15 to 100 Hz, independent of curve shape, on requests and voltages.

Non-linear graduations at the beginning of the scale allows reading from approximately 15 % of measuring range onwards. Ammeter also has indicator range for double value of rated current (overcurrent scale) whereby the overload range is non-lineary graduated. Both versions are available. For milliammeters the measuring and indicator ranges coincide.

The special case design allows quick dial exchange. This is especially suitable for instruments which are connected to current or voltage transformers (xA/1A, xA/5A, xV/100V, xV/110 V).

The exchangeable dial has a number of advantages:

• quick and simple adaptation of the instrument to variable user technical requirements

• shorter delivery time

• allows flexible planning

Special versions are available for panel mounting into ships. These are mechanically resistant and additionally sealed instruments which comply with the requirements of Lloyd registers. The instrument case is marked by an anchor and a capital letter L at the end of the type designation.

Features:

• For measurement of AC currents and voltages

• Good read-out survey on larger distance

• Exchangeable dial

• Resistance to mechanical vibrations

• Protective cover for terminals (optional)
