What is the important role of insulation resistance tester in testing?
Insulation resistance tester, also called megohmmeter, is used to check the insulation resistance of electrical equipment, household appliances or electrical wiring to ground and phase to phase, in order to ensure that these equipment, electrical appliances and wiring work in a normal state, to avoid accidents such as electrocution casualties and equipment damage. Today to give you an explanation of insulation resistance tester in the detection of what important role.

How insulation testers reduce the risk of battery insulation fires
Continued growth in energy demand (energy demand) and performance improvements have led to the rapid maturation of lithium-ion batteries in large energy-intensive applications such as electric vehicles (EVs) and various renewable energy storage systems (ESSs). However, with the rapid growth in battery usage, energy density, and high-speed charging and discharging has come an increase in fire and explosion incidents.
How does a loop resistance tester perform synchronization and timing control of a digital power supply?
Loop Resistance Tester is a special instrument for contact resistance and loop resistance measurement of switching control equipment. The test current adopts the 100A DC recommended by China's standard GB763, and the loop resistance or contact resistance can be measured directly under 100A, 200A, 300A, 400A, 500A or 600A current. So, how does the loop resistance tester perform the synchronization and timing control of the digital power supply? The following article takes a look at this.
Insulation resistance tester use and precautions
Ensure that the test article is safely grounded and not energized. Ensure that the E terminal (ground terminal) of the meter is grounded. Ensure that the battery is fully charged, if the "Under Voltage" lamp is lit it will not be possible to test properly.
Insulation tester use specification
I. Operating Procedures 1. Insert the positive and negative connectors correspondingly into the positive and negative ports behind the main unit, respectively (positive: detection handle end; negative: crocodile clip connection end).
Insulation monitor principle and common failure analysis
An insulation monitor is an instrument used to monitor the insulation status of electrical equipment, which judges the insulation status of electrical equipment by measuring insulation resistance. Its working principle is mainly based on the relationship between voltage and current, common insulation monitor using AC power supply, the test voltage applied to the electrical equipment under test, through the measurement of current to calculate the insulation resistance.
Insulation resistance tester, also called megohmmeter, is used to check the insulation resistance of electrical equipment, household appliances or electrical circuits to ground and phases to ensure that these equipment, electrical appliances and circuits are working in a normal state to avoid electric shock, casualties, and equipment damage. accident.
