What symptoms indicate problems with an industrial electrical installation?
Many companies only discover electrical installation problems when there is a standstill or equipment failure — then the repair costs are significantly higher than a preventive inspection. The most common warning signs are: frequent breakdowns of fuses or protective switches, voltage fluctuations during the operation of machines, overheating of cables or connectors, unstable operation of PLC controllers and increased electricity consumption for no apparent reason. Each of these symptoms is a signal that the electrical infrastructure is not working in optimal parameters. Delays in resolving these issues lead to unforeseen downtime, potential security incidents, and loss of productivity that quickly adds up to significant financial losses.
When does it make sense to invest in upgrading an existing electrical installation?
The upgrade of the electrical installation makes sense when the existing infrastructure does not support new machines or the extension of the production line when the installation does not meet current safety standards (e.g. IEC 60364) or when the company plans to introduce automation and integration of control systems. A preventive inspection every two to three years is recommended for all industrial plants operating in challenging conditions — high temperatures, humidity or vibrations accelerate the aging of cable infrastructure and connectors. Professional examination includes thermographic analysis of junction boxes, measurements of insulation resistance and examination of documentation. Based on the survey, a detailed upgrade plan is drawn up, which minimizes production downtime during the execution of works.
