Overview
The "IP probe" is a professional testing tool used to verify the degree of protection of the enclosure of electrical equipment (IP rating), mainly detecting the equipment's ability to resist the intrusion of solid foreign objects. According to the first digit in the IP rating (such as IP1X to IP4X), the corresponding probe specifications and testing requirements are different:
Core functions and classifications
IP1X test probe (test tool A):
A rigid sphere with a diameter of 50mm, used to simulate the intrusion test of solid foreign objects with a diameter of ≥50mm (such as large tools or palms), suitable for the protection verification of outdoor distribution boxes, large machinery and other equipment.
IP2X test probe (test tool B):
A knuckle - shaped probe simulating the shape of a finger (with a diameter of 12.5mm), with a thrust of 10±1N, used to detect whether the equipment can prevent fingers from touching the internal live parts. It is commonly used in the electric shock prevention tests of household appliances, lamps and other products.
IP3X test probe (test tool C):
A rigid straight rod with a diameter of 2.5mm, with a thrust of 3±0.3N, used to simulate the intrusion of thin sticks or tools, suitable for scenarios such as industrial control cabinets and power tools that need to block smaller solid foreign objects.
IP4X test probe (test tool D):
A rigid straight rod with a diameter of 1.0mm, with a thrust of 1±0.1N, specially used to test the equipment's protection ability against fine particles such as sand, dust and metal shavings, and is widely used in equipment in dusty environments such as outdoor lamps and communication base stations.

Application
Industrial and Outdoor Equipment: The IP4X probe is often used for equipment testing in dusty environments such as deserts and mines, such as construction machinery and marine electrical appliances, to ensure that dust cannot penetrate and cause malfunctions.
Electronics and Precision Instruments: The IP3X probe can verify the dust-proof capabilities of sensors and medical equipment, preventing fine metal shavings from damaging precision components.

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.
