Electric Power System
The transformer, as an important measuring instrument, is used in the power system, which makes the high voltage and current visible through the transformer. The transformer can measure the voltage, current and electric energy of the primary system in combination with measuring instruments and metering devices. Together with the relay protection and automatic device, it can constitute the electrical protection and automatic control of various faults in the power grid. The performance of transformer directly affects the accuracy of power system measurement and measurement and the reliability of relay protection device.

Split Core Current Transformers in Industrial Motor Maintenance: A Case Study
Industrial electric motors are the workhorses of modern manufacturing, driving pumps, fans, conveyors, compressors, and countless other machines. Their unscheduled downtime can result in catastrophic production losses, costly repairs, and significant safety hazards. Consequently, proactive and predictive maintenance (PdM) strategies have become paramount for ensuring motor reliability and optimizing operational efficiency. At the core of many PdM programs lies the continuous or periodic monitoring of motor electrical signatures.

Analysis of Rated Short-Time Thermal Current and Dynamic Stability Current Parameters for Current Transformers
prevents mechanical failure. Proper selection, based on system short-circuit calculations and adherence to standards, is essential for maintaining power system reliability. Engineers must balance both parameters to avoid under-sizing (risk of CT failure) or over-sizing (increased cost). As power systems evolve with higher fault levels (e.g., due to renewable integration), these parameters will remain central to CT design and application.
