SATEC’s range of current transformers referred to as High Accuracy Current Sensors (HACS) are designed for flexibility for new and retrofit applications for Energy Metering. SATEC HACS used with SATEC Electrical metering hardware EM132, EM133, PM130EH, PM135EH, BFM136 provide a complete system measuring accuracy of Class 1.0 or better (energy meter + HACS = Class 1.0 or better).
The HACS can be extended up to 200 metres from any SATEC meter using 1.5mm2 cable providing solutions where restrictions to access to loads is difficult due to installation problems.
The SATEC HACS have an accuracy Class 0.5, providing readings as low as 0.1% of the current range. HACS are available in 100A, 200A, 400A, 800A, 1200A, 2000A and 3000A current ranges.
Interfacing with third party CT’s already installed in the field with existing installations is possible with the SATEC HACS via the secondary of the 5A or 1A input with appropriate programming of the SATEC meter to suit the installation.
