Description
With over 100,000 units installed in different commercial, industrial, residential and utility applications, SATEC HACS CTs are your go-to for a safe facility, easy installation and high accuracy, which is what metering is all about.
HACS Safety Feature
SATEC HACS feature an electronic switch which provides an automatic protection circuit for maximum safety.
This prevents the fires and explosions, discussed above, which unfortunately occasionally occur when standard CTs are improperly disconnected.
Marketing Materials
Maximum Accuracy
Standard energy meters feature current inputs typically rated at 5A or 1A, making the meter reliant on an external CT to step-down standard distributed electrical currents.
These two stepdown transformations (external + internal) result in a combined error which is the product of an aggregation of factors:
- Meter error: affected by amplifiers, A/D converters, passive components and noise resulting from circuit design
- Meter's built-in CT error
- External CT error
- CT phase shift: an additional parameter affecting accuracy, varying, even within the same product of any manufacturer, from one batch to the another
SATEC designs its meters in compliance with a minimal accuracy standard of Class 0.5S. Many SATEC products feature a yet more advanced accuracy standard of Class 0.2S. To guarantee overall system accuracy, featuring a minimal metering error, SATEC designed the HACS CTs.
HACS feed their secondary current outputs directly into corresponding designated SATEC meter models which feature low current inputs (mA).
Maximum Convenience
- Benefit from the protection circuit with any disconnection initiated - no shorting blocks needed!
- The extremely low burden which characterizes the HACS allows the user to run wiring from the meter to loads positioned up to 200 meters away from the SATEC power-meter, without any compromise whatsoever on accuracy, employing wiring as thin as 16 AWG.
Standard Compliance
- IEC 61869-1 Instrument transformers - Part 1: General requirements
- IEC 61869-2 Instrument transformers - Part 2: Additional requirements for current transformers

Installation Recommendations
All HACS include a built-in automatic protection circuit for maximum safety, eliminating the need to use shorting bars.
- All HACS are supplied with 8ft / 2.5m cable.
- Maximum cable length: 650ft / 200m.
- Recommended wire gauge: ≥1.5 mm2
It is recommended to use a shielded twisted extension cable to connect between the HACS and the SATEC meter. The cable shield must be connected to protective ground.
It is recommended to locate HACS cable in separate cable conduit and at least 1m (3ft) away from High Voltage circuits, and / or other high power magnetic fields.
HACS Configuration In Metering Unit
When configuring the meter, make sure to set the value of the HACS CT primary current, either via the front panel of the unit or via the PAS software.
Set the “Primary current” value in the unit configuration as HALF the value stated above in sheet as “RATED CURRENT”, per each HACS CT model. e.g., for the CS4S model, rated at 400A, feed “200” as primary current.
RS5 Primary Current: the RS5 model stands as an exception, in which the value entered is “5”.
Configuring the PM180 analyzer: rated values vary when configuring the product. Please consult the PM180 manual.
