Introduction to Current Transformers (CTs)
A current transformer is an instrument transformer in which the secondary current is substantially proportional to the primary current and differs in phase from it by an angle which is approximately zero.Continue reading
Segmented Core Cap Technology for Medical Transformers
A novel "segmented core cap" design for medical-grade isolation transformers supports primary and secondary windings in alternate sectors to reduce leakage current.Continue reading
Medical Grade Isolation Transformer Design
Medical grade isolation transformers are designed to isolate the patient and the operator from an electric shock and to protect the equipment from power surges or faulty components.Continue reading
Using Transformers for Electrical Isolation in Medical Devices
Toroidal transformers are ideal for electrical isolation in medical equipment because they are compact, can be completely encapsulated when necessary, and have low stray fields, making them less likely to cause electromagnetic disturbances.Continue reading
Leakage Current in Medical Devices
Medical electrical equipment, even though operating perfectly, may still be hazardous to the patient. This is because every piece of electrical equipment produces a leakage current. Learn how proper design ensures patient safety.Continue reading
