New Splitcore Transformer Enhances Electrical Monitoring Safety
The electrical industry is witnessing a significant advancement in current measurement technology with the introduction of innovative split-core current transformers. These devices combine installation convenience with high-precision performance, addressing long-standing challenges in power monitoring and protection systems.
The new transformer design features a snap-on connection mechanism that eliminates the need to disconnect main circuits during installation. Its compact and lightweight construction allows for effortless mounting on cables of various specifications, even in confined spaces. This innovation significantly reduces installation time and labor costs for both new projects and system upgrades.
Engineered for precision, these transformers offer a working frequency range of 50Hz-2kHz and measurement capability from 10% to 130% of nominal current. Key performance features include:
- ±1.0% ratio accuracy
- ±60 minute phase displacement
- Wide measurement range from 5A to 630A
- Dielectric strength of 2.5KV/1mA/1min
- Insulation resistance of 500V/100MΩ minimum
The fully encapsulated design provides robust mechanical performance and environmental resistance, while premium silicon steel cores ensure measurement stability across diverse operating conditions.
Manufactured with safety as a priority, the transformers feature:
- PA housing material with 94-V0 flame retardant rating
- PBT framework for structural integrity
- Internal snap-on mechanism for secure connection
- 1.5m PVC three-core shielded twisted pair output cable
The devices operate reliably in temperatures ranging from -25°C to +75°C and environments with up to 85% relative humidity.
These split-core current transformers serve multiple sectors:
- Industrial automation for monitoring motors and transformers
- Energy management systems for load optimization
- Smart grid infrastructure for distribution monitoring
- Renewable energy systems including solar and wind installations
- Building automation for power load management
The transformers are available with either 0.333V (AC) or 0-500mA output options, providing flexibility for different monitoring system requirements.
