Remote regions often have unstable three-phase power. Voltage drop or surge can damage compressor motor winding. When voltage deviates more than ±10% from rated value, continuous operation is not recommended for cold storage piston refrigeration compressor.
Phase loss protection is a must-have function. Once one phase is disconnected, motor still rotates with abnormal current, which burns winding within several minutes. Integrated protector cuts off power immediately upon phase loss detection.
Soft starter is widely applied for large piston compression unit. It limits starting current and reduces impact to weak local power grid. Direct-on-line starting creates huge current spike, triggering grid protection and tripping nearby electrical equipment.
Lightning surge protection is required for outdoor power lines in mountain cold storage. Surge protector diverts lightning induced impulse voltage, preventing breakdown of compressor control board and motor insulation.
xtldcool piston refrigeration compressor factory can pre-install integrated power protection module on compressor control panel for remote cold storage. The module records abnormal power events for post-fault analysis.
Operators should regularly test protection function every quarter. If voltage protection fails, compressor may run under abnormal power and lead to expensive motor burnout repair.
