The isolation transformer plays a crucial role in the protection of photovoltaic systems connected to the distribution line. Its inclusion becomes essential to prevent harmful disturbances generated by DC components from affecting the AC line.
In situations such as a short circuit on the individual PV cell or a fault in the inverter, the absence of an isolation transformer could cause such problems to propagate to the AC distribution line, generating potential failures to loads or other connected generation sources.
To ensure high reliability and safety of the system, our customer has approached Ortea and gave the specifications of the system.
The solution provided was a 250kVA K4 isolation transformer specifically designed and manufactured inside an IP54 cabinet for outdoor installation.
With this tailor-made solution, power quality problems in the PV system are avoided, ensuring stable and reliable power production.
