In this post, we will only have an overview of common faults and solutions in photovoltaic power plants. Different types of PV power plant and operating environments may cause other types of faults, which require specific analysis and resolution. Regular maintenance and inspection are important guarantees for the normal operation of photovoltaic power plants. 1. […]

According to the voltage level, power cables can be divided into low-voltage power cables and medium voltage power cables. How should we distinguish them? Generally , low-voltage cables are used to transmit power cables below 1kv, while medium voltage cables are used to transmit power cables between 1kv and 35kv. From the structural point of

We think, the following reasons should be considered (1) During normal operation, due to various reasons, the metal sheath of the cable may generate induced voltage, especially when single core power cables are laid in parallel; (2) When insulation breakdown or system short circuit occurs in an electrical system, due to the large fault current
