Structural features of the ammeter
Ammeter to the apparatus for testing current transformers - instruments in which the measuring system is assembled by astatic scheme that reduces the influence of external magnetic fields up to allowable limits. The common axis of the ammeter placed between two identical bonded parts are movable. Exposing them to a magnetic field while imparting rotational moments are mutually opposite directions, which balance the system.
Conditions of operation of ammeters
The ammeter in terms of mechanical stress during operation applies to ordinary.
Ammeters are designed for operation at temperatures between +10°C to +35°C. the relative humidity for optimum performance ammeter should not be more than 80% (at +30 º C).
