Why Regular Transformer Maintenance Matters: 5 Serious Consequences of Neglecting ItI. Allowable TemperatureWhen a transformer is in operation, its windings and iron core generate copper loss and iron loss. These losses are converted into heat energy, causing the temperature of the transformer's iron core and windings to rise. If the temperature exceeds the allowable value for a long time, the insulation will gradually lose its mechanical elasticity and age.The temperature of each part of the transformer during operation is different: the winding temperature is the highest, folRockwell09/12/2025 -
How to Implement Condition-Based Maintenance for Power Transformers? A Complete 4-Step Process Analysis1. Definition of Condition-Based MaintenanceCondition-based maintenance refers to a maintenance method where decisions on whether and how to perform maintenance are determined based on the real-time operating status and health condition of equipment. It has no fixed maintenance methods or schedules. The prerequisite for condition-based maintenance is the establishment of equipment parameters and the comprehensive analysis of various operational information of the equipment, so as to make reasonaNoah09/12/2025 -

High harmonics? Your transformer may be overheating and aging fast.This report is based on the analysis of one-day power quality monitoring data of your company's distribution system. The data shows that there is significant three-phase current harmonic distortion in the system (with a high total harmonic distortion of current, THDi). In accordance with international standards (IEC/IEEE), harmonic currents at this level have posed substantial risks to the safe, reliable, and economical operation of the power supply transformer, mainly manifested in additional hLeon09/12/2025 -
Ultimate Guide to AC Contactor Abnormal Noise: From Electromagnetic Noise to Mechanical Vibration, Accurate Diagnosis and HandlingIn electrical control systems, AC contactors are among the commonly used electrical components, and they are also a common source of various electrical faults. After long-term use—especially in harsh environments with high levels of dust—AC contactors may sometimes emit squeaking or rattling noises after being pulled in and held. The causes of this phenomenon are analyzed as follows.Squeaking Noise After Pull-In and HoldingA fully functional AC contactor makes no noise when energized and pulledFelix Spark09/11/2025
