Current sensor

Announced option of its new 5300 series of current sensors and transformers that measure an array of AC currents by transforming them accurately from high to low measurable values.

API’s 5300 series have a wide primary current array of 3.5 Amps to 800 Amps, and are available in various kinds of current transformers, including low phase/high accuracy as well as high frequency. Current transformers possess a wide operating frequency range of 20 kHz-100 kHz and could be totally encapsulated, without or with wound primary turns and loading resistor. All current sensors and transformers are designed to meet the relevant UL, ANSI, VDE, CE, and MIL standards. In addition, API now offers EMRL current transformers that have been designed to conform to standards for electrical and electronic measuring test equipment.

These current sensors and transformers are generally utilized in applications likes advanced fault tolerant computers and workstations, metering, protective relays, control panels reading current flowing to electric transformer, ampmeters, wattmeters and cross current compensation, in addition to telecom and communications.

Current sensors detect electrical current inside a wire and develop a signal proportional into it, which can be then employed to display the measured current, or stored for more analysis inside a data acquisition system. Similarly, current transformers are utilized to measure alternating electric currents. When current inside a circuit is too high, a present transformer generates a reduced current which is accurately proportional, so it could be conveniently associated with measuring and recording instruments.
