Current sensors/transformers measure a wide range of currents

September 20, 2013 // By Julien Happich
API Technologies’ new 5300 series of current sensors and transformers measures a wide range of AC currents by transforming them accurately from high to low measurable values.

The current sensors feature a wide primary current range of 3.5A to 800A, and are available in several types of current transformers, including low phase/high accuracy and high frequency. Current transformers have a wide operating frequency range of 20kHz-100kHz and can be totally encapsulated, with or without wound primary turns and loading resistor. All current sensors and transformers are built to meet the relevant UL, ANSI, VDE, CE, and MIL standards. In addition, API also offers EMRL current transformers which were designed to comply with standards for electrical and electronic measuring test equipment.

Current sensors detect electrical current in a wire and generate a signal proportional to it, which is then utilized to display the measured current, or stored for further analysis in a data acquisition system. Similarly, current transformers are used to measure alternating electric currents. When current in a circuit is too high, a current transformer produces a reduced current that is accurately proportional, so it can be conveniently connected to measuring and recording instruments.
