Insulation performance test method under humid conditions

In order to ensure the insulation performance of photovoltaic modules in humid environments, operation and maintenance personnel should regularly conduct insulation resistance testing. This helps detect potential insulation problems in a timely manner.

Purpose and evaluation of moisture insulation testing systems

The main purpose is to evaluate and ensure that the insulation performance of the module is not damaged in a humid environment, thereby preventing corrosion, leakage and other problems caused by moisture intrusion, thereby avoiding accidents.

Humid environments have a significant impact on the insulation performance of equipment. Research shows that a humid environment will cause the insulation resistance of the insulating material to decrease, thus affecting the normal operation and safety of the equipment.

To effectively detect and prevent moisture intrusion, a variety of techniques and methods can be employed. For example, distributed sensor wires are used to monitor temperature differences within insulation to determine if moisture has intruded.

Wet Leakage Current Tester ME-PV-WLC photovoltaic module wet insulation testing system tests the insulation performance of the module under humid working conditions and detects whether moisture from rain, fog, dew or melted snow enters the working part of the internal circuit of the module, causing corrosion and leakage. Applicable to IEC61215 standard MQT15 clauses and IEC61730 MST17 clauses.
