Photovoltaic and optical cable splicing process
It describes three main splicing methods - de-matable connectors, mechanical splices, and fusion splices. The need for durable and reliable medium voltage (MV) cable splices is critical in solar power plants, where extensive networks connect photovoltaic arrays, inverters, and transformers. Given the harsh environmental conditions these cables are subjected to, proper splicing techniques are essential. Fiber optic splicing is the process of joining two fiber optic cables together so that light signals can pass with minimal loss or reflection. This article delves into the multifaceted world of cable splicing, particularly in applications for renewable energy. Optical fiber splicing requires that the additional loss of the optical fiber connector is small, the connector has high reliability, has good mechanical properties, and maintains long-term stability of characteristics; on-site construction requires simple operation, short splicing time, and low. This document discusses optical fiber splicing.

Using a clamp meter to test a photovoltaic DC cable
This guide explains how to correctly measure DC current in PV systems, what to watch out for, and how to obtain reliable results in real-world solar applications. In a PV system, DC current is measured by clamping a DC-capable clamp meter around a single DC conductor. Traditionally used by electricians for measuring current without breaking the circuit, a modern clamp meter, particularly one with DC voltage. Unlike traditional inline measurements, a DC clamp meter allows you to measure current safely without disconnecting the circuit, making it the preferred tool for live PV systems. This helps determine the panel's efficiency and identify any performance issues. Testing is usually conducted under standardized conditions to ensure accurate results. You may also use an IV curve. A clamp meter is a clothespin-shaped instrument that can be clamped around a live wire in order to measure the current it's carrying.
