Electrical inspections and testing
LV and MV inspections of installations, solar PV, lightning protection and switchboards by our own inspection technicians. An inspection report, and deadlines we keep track of for you.
- 1Inspection and testing of distribution, PV and switchboardsInitial and periodic, LV and MV, under vyhláška 508/2009 Z. z. (Slovak decree on technical equipment).
- 2Lightning protection and earthingAir terminals, down conductors, earthing system, earth resistance measurement.
- 3Thermal imaging diagnosticsConnections, switchboards and strings under load, report with images.
An inspection is not a stamp; it is proof that your operation is safe
The operator of electrical equipment is responsible for its condition. During a labour inspectorate check, after an accident or in an insurance claim, the inspection report is the first document requested. A missing or expired inspection means a penalty and a dispute with the insurer.
We inspect LV and MV equipment, solar PV plants, lightning protection, switchboards and machinery. You receive an inspection report, defects with proposed remedies and deadline records that remind you in advance.

How we work together
- 01
Site visit and records
We go through the equipment and documentation, set deadlines according to the environment and record them.
- 02
Quote and schedule
A fixed price based on scope, dates planned so your operation does not stop.
- 03
Measurement and inspection
The inspection technician measures, inspects and documents. Defects are recorded with proposed remedies.
- 04
Inspection report
The report, measurement records and, with thermal imaging, the images. For serious defects, a repair plan.
- 05
Deadline tracking
We remind you before a deadline expires and propose a date. With a service contract this runs automatically.
Not sure when your deadlines expire?
Send us a list of equipment or your last inspection report. We will tell you what is overdue and what needs to be dealt with first.
Why do it with us
Our own inspection technicians
Inspections are carried out by employees authorised for LV and MV. Energovision is responsible for the report and the deadline.
One partner for inspections, service and repairs
We fix a defect with our own electricians and modify the switchboard in our own production.
Deadline records
Every piece of equipment has a deadline and an advance reminder in our records.
495+ projects
From family homes to megawatt plants and transformer stations.
One project, six services
It is rarely just one thing. On a single delivery we also handle what sits upstream and downstream in the circuit.
Questions we get asked
1What inspection intervals apply to my operation?
Intervals are set by vyhláška 508/2009 Z. z. according to the type of equipment and the external influences of its environment. They differ for a normal indoor environment and for wet, dusty or explosive ones. The inspection technician determines the exact intervals for your equipment at the initial visit and enters them into the records we track for you.
2How much does an inspection cost?
The price depends on the size of the installation, the number of switchboards and circuits and the environment. After a site visit or based on the design documentation we give a fixed quote. Inspection and testing are included in the PREMIUM service packages and in transformer station management.
3How long does an inspection take and what should I prepare?
A smaller building takes one day; an industrial operation depends on the scope. Prepare the design documentation, previous inspection reports and access to the switchboards. If documentation is missing, we prepare it as part of the inspection.
4What is an initial and what is a periodic inspection?
The initial inspection and test is carried out before new or refurbished equipment is put into operation. The periodic one is repeated at the intervals set by the decree throughout operation.
5Do you also inspect households?
Yes. Inspection of a family home's electrical installation, lightning protection and solar PV, usually in one visit. For solar PV on a home we recommend an inspection every 4 years.
Non-binding enquiry
Tell us what equipment you have and when it was last inspected. We will get back to you by the next working day with a date for a site visit or a price based on the documentation.
