For engineers and procurement teams looking for a reliable solution for current transformers in industrial automation projects, SPS 2026 in Nuremberg will be an important opportunity to: compare real products, technical possibilities and supplier support. SPS 2026 takes place from 24 to 26 November. The official profile of SPS includes intelligent and digital automation from sensors to intelligent system solutions.
HEYI presents a wide range of products for current transformers for automation systems, industrial control cabinets, power monitoring, leakage protection and modernization projects.
1. Why do automation engineers need better electricity monitoring?
1.1 Compact industrial control cabinets require smaller KT solutions
In modern factories, control cabinets often include PLKs, VFDs, servo drives, power meters, protection relays and communication modules. Limited cabinet space complicates the choice of CT.
For this type of project, HEYI offers:
● KCT, DP, HK split core current transformer series shared core current transformers for upgrade assembly
● MSQ, CP, SDH, LMK window type current transformer series for standard cabinet assembly
● HYCA and ZCT leakage current monitoring sensors for residual current and zero-sequence current detection
These products help engineers create safer and more reliable electrical monitoring systems without altering the entire cabinet construction.
1.2 Modernization projects require rapid installation
Many European works cannot stop production for a long time. When engineers need to add monitoring to existing cables, a split core current transformer is often the practical choice.
The HEYI KCT, DP and HK series are available in:
● Existing distribution restrictions
● Engine control
● Improved energy monitoring
● Automation modernization projects
● Computing systems for buildings and factories
The shared core structure helps reduce drive changes and installation times.

2. How can power transformers support industrial automation?
2.1 Current monitoring of PLCs and automation systems
The stable current sensor for automation helps engineers control engines, pumps, compressors, conveyors and production facilities. On automated production lines, current data can be supported:
● Equipment condition monitoring
● Detection of an abnormal load
● Analysis of energy consumption
● Preventive care
● Signal input for signalling and protection
HEYI current transformer products can be integrated with power meters, controllers, monitoring modules and industrial switches.
2.2 Current transformer for industrial control cabinets
Reliable current transformer for industrial control cabinet projects needs different cabinet models, circuit sizes, accuracy requirements and installation methods.
For the manufacture of new cabinets, the current transformers MSQ, CP, SDH and LMK from HEYI are suitable for standard line constructions and batch assembly.
For upgrading existing cabinets, the KCT, DP and HK split core current transformer series of shared core current transformers are suitable when engineers need to install around existing cables.
For leak protection and fault monitoring, the HYCA and ZCT zero current sensors can be used in systems requiring residual current detection.

3. Which HEYI products will be presented at SPS 2026?
3.1 KCT, DP, HK: split core current transformer solutions
HEYI shared-core products are designed for projects where speed of installation and flexibility of upgrade are important.
Typical applications are:
● Monitoring of plant performance
● Energy Management Systems
● Commercial distribution plates
● Engine control boxes
● Automatic cabinet update
These products are particularly useful when engineers need a current transformer that can be installed without cutting the main conductor.
3.2 MSQ, CP, SDH, LMK: solutions for window current transformers
The CT HEYI window range is suitable for cabinet OEMs, switchgear manufacturers and electrical panel manufacturers.
Typical applications are:
● low voltage switch
● Industrial Distribution Restrictions
● Performance measurement systems
● Relay protection systems
● Current measurement at the equipment level
For purchasing teams, these series are also suitable for stable batch delivery and individual project requirements.
3.3 HYCA and ZCT: Leak Flow Monitoring Sensor Solutions
In modern automation systems, leak current monitoring is becoming increasingly important, especially in environments with FDVs, power electronics, electric vehicles and industrial power sources.
HEYI HYCA and ZCT products can:
● Monitoring of remaining currents
● Recognition of Nullstrom
● Monitoring the Errors of the Earth
● Protection of electrical safety
● Warning of automation system errors
These sensors help engineers improve system safety and reduce hidden electrical risks.
