When using the inverter, the leakage protector must not be used. This is a major principle for the use of the inverter. Some customers choose the corresponding leakage protector for the inverter when using the inverter. The final result: as soon as the inverter starts, the leakage protector starts, and the system cannot run at all. The principle of the leakage protector is that the zero sequence current is zero. When using the inverter, the zero sequence current cannot be zero. The output side of the inverter is a PWM wave, and there is a capacitive effect of a long cable between the motor cable and the ground. When a cable with a shielding layer is used, the capacitive effect is more obvious. When the inverter is working, the capacitor is charging and discharging, and the current flows into the ground through the capacitor, and then flows back to the inverter from the ground wire on the incoming side to form a current loop. If an earth leakage protector is used on the incoming side, it will act to cut off system operation. So, don't equip your inverter with a leakage protector. If you want to ensure safety, do a good job of grounding the equipment. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #inverter #forfrequencydrive #ACvfd #ZJSHUYI #chinashuyi #shuyitop #chinafactoryinverter #variablefrequencydrive #electricdrive #chinavfd #acvariablefrequencydrive #acdrivesandvsd #ACvfdprice
