LISUN’s transformer test solutions are designed to meet the comprehensive requirements of international standards, providing professional support for testing transformers, reactors, power supply units, and their combinations. IEC 61558-1:2017 establishes extensive safety requirements and test specifications for these products, covering aspects such as electrical insulation, mechanical strength, and protection against electric shock, laying a solid foundation for ensuring product safety in various applications. IEC 60076-1:2011 focuses on power transformers, defining key concepts, rated values, and operating conditions, serving as a fundamental guide for their design, manufacturing, and operation. IEC 62041:2010 addresses electromagnetic compatibility (EMC) requirements, specifying emission and immunity limits to ensure these products coexist harmoniously in the electromagnetic environment without causing or being affected by excessive interference.
LISUN’s transformer test solutions cover key items in relevant standards with professional equipment, enabling diverse tests: insulation/creepage checks, hazardous part identification, touch current measurement, test probe-related tests, and assessments of heat resistance, humidity, aging, rust resistance, vibration, tumbling, impact resistance, and enclosure protection. They also include material flammability, fire/heat resistance, tracking resistance, impulse dielectric performance, short-circuit impedance, voltage drop, temperature rise, total harmonic content, and EMC tests (electrostatic discharge, radiated fields, fast transients, surges, etc.). One-stop support helps manufacturers and laboratories ensure products meet international standards, guaranteeing safety, reliability, and stable performance in use.
