The PT Series has been designed specifically for primary injection testing of circuit breakers, protective relay equipment & other applications that require high variable currents.
This system consists of a portable control unit and current unit.
This system is intended for use in high voltage substation and industrial environments.
The AVN 903 is a very reliable decade resistance box with high quality rotary switches providing in line readouts. Ideal for laboratory, educational and calibration applications. The extra terminal forms an accurate potential divider.
The DM 905 is a 5 decade capacitance box giving a useful range of capacitance values. Specialised for use in calibration areas : education and laboratories.
