What is Peak Inverse Voltage (PIV)?

1. On a scorching sunny day, do damaged vulnerable components need to be replaced immediately?Immediate replacement is not recommended. If replacement is necessary, it is advisable to do so in the early morning or late afternoon. You should contact the power station’s operation and maintenance (O&M) personnel promptly, and have professional staff go to the site for replacement.2. To prevent photovoltaic (PV) modules from being hit by heavy objects, can wire mesh protective screens be install

1. What are the common faults of distributed photovoltaic (PV) power generation systems? What typical problems may occur in various components of the system?Common faults include inverters failing to operate or start due to voltage not reaching the startup set value, and low power generation caused by issues with PV modules or inverters. Typical problems that may occur in system components are burnout of junction boxes and local burnout of PV modules.2. How to handle common faults of distributed

1. Definition of High-Voltage Cable Line Constant TestingHigh-voltage cable line constant testing refers to the systematic measurement, using specialized instruments, of electrical parameters such as resistance, inductance, capacitance, and conductance before a cable line is commissioned or after major maintenance. The aim is to obtain fundamental data characterizing the electromagnetic properties of the cable, serving as a critical testing phase that provides accurate parameter support for powe

1.Work Environment Requirements and Safeguard MeasuresBased on technical requirements for cable equipment storage, laying, transportation, laying, transposition, testing, and cable terminations, the project owner and construction units have conducted extensive trials and implemented protective measures regarding ambient temperature, humidity, bending radius, traction control, and route optimization. These measures ensure high-voltage cable quality and on-site safety under harsh winter conditions
