ept Services GmbH

ept Services was founded in 2010 and is engaged in the planning, project drawing, assembly and commissioning of electrical energy supply systems and their infrastructure, as well as data technology.

We are specialized in the field of electrical energy supply systems. At our production site in Hamburg we produce low-voltage switchgear as well as safety and control cabinets. Furthermore we carry out the secondary technical equipping of medium voltage switchgear. With our partners we deliver custom-made concrete stations and container facilities.

Range of Services

Planning and designing
Calculation and layout of electrical energy systems is a fundamental working step in the integral assessment and execution of projects. We offer you load and short circuit calculations for the different switching states of your net, the laying of cables, current and voltage transformers as well as further electrical equipment together with a cost and use-of-potential analysis.
We also examine transient and sub-transient cut-in processes of transformers, carry out flicker analyses and offer earth termination studies.
The software we use is: PSS Syncal, Matlab, SiCab, CTDim, AutoCAD, Engineering Base.

Project realization
We offer advice with regards to choosing products and suppliers, structural measures and scheduling. We deliver the chosen components, carry out the assembly and the start of operation. For this, we provide you with our staff with many years of experience in low- and high voltage technology.

In our manufacture we produce low voltage switchgear, safety -, control – and switch – cabinets as well as medium voltage switchgear. In our production hall, next to copper and aluminum processing, we have our in-house production of safety – and control – technology. We equip gas – and air – insulated medium voltage switchgear components as desired by the customer.
Factory acceptance tests are carried out in our production hall.

Commissioning and analysis
When putting systems into operation and analyzing them, we employ worldwide approved measuring systems and test according to the corresponding valid norms. The tests are executed by qualified and trained engineers.

For the primary technical inspection we use products of the CPC-range of the company Omicron. For safety inspections we exclusively employ 3-phase inspection systems of the CMC production series of the company Omicron.
We also use test devices of renowned manufacturers like Megger, Gossen Metrawatt or b2.
