Bergoz ACCT

The ACCT is non-interceptive current transformer. It consists of a toroid sensor with inner diameter up to 178 mm (larger on request) and an active electronics circuit in a small box. Cable from toroid sensor to electronics can be twenty meters long maximum.

The ACCT is an evolution of the active transformer first proposed by Hereward in 1960. Compared to the Hereward transformer, the ACCT presents much lower noise, a DC offset of the output reduced to a very small value and excellent long-term stability.

The sensor is built with a single winding, which requires only one wire pair between sensor and electronics; this allows much better EMI rejection when long cables are used. The electronics circuit is multistage, implementing the best low-noise operational amplifier available for this application.

Features

Output current range range from ±10mA to ±2A full scale.
Frequency response from 5Hz to 350kHz
DC current up to 1A does not saturate the sensor
Sensor inner diameter from 16 to 198.4mm (larger diameters available upon request)
Radiation hard sensors available.

Applications

Measurement of long pulses and macro pulses.
Efficiency measurement between transfer lines and storage rings.
Single bunch monitoring.
Timing calibrations.
