How insulation testers reduce the risk of battery insulation fires

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?

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 monitor principle and common failure analysis

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.
