Power System Studies
An electrical distribution system that functions optimally is essential for a reliable power supply. Every new load, expansion, upgrade and configuration change in your network can produce conditions for which your network was not originally designed. If there are faults in the protection system, any relatively small errors such as overloads, short circuits or earth faults can lead to significant financial damage as a result of uncontrolled interruptions to the voltage in your company.
The network studies conducted by Eaton — Electrical Services & Systems (E-ESS) show where critical points occur in your network. We provide you with information so that the right decisions can be made when planning upgrades or expansions of your electrical system. This results in lower operational costs, greater availability and minimum risk of faults.
Studies provide an insight into the minimum and maximum fault currents in the system during a short circuit.
Load flow, power factor correction
The purpose of a load flow calculation/load calculation is to calculate the prevailing voltages, currents and capacities as well as the grid losses in a network during normal operation and often also after failure of a single component.
Motor start simulations
Motor start studies evaluate the impact of starting large motors on the rest of the system. The simplest method is to use the load flow calculation to determine the terminal voltage of the motor when it is switched on. If greater accuracy is desired or needed, the entire starting phase with respect to time is simulated using software.
Harmonics
Measurements can be used to perform an analysis of harmonics in the local network and the harmonic emission of individual appliances. Harmonic distortion, created for example by frequency converters for speed control, high-pressure lamps, electronic ballasts and computers, can cause many problems in practice such as: distortion of the mains voltage, neutral conductors that carry too much current, extra heat and loss of efficiency in motors and transformers. This can lead to accelerated aging of equipment and additional loss of energy.
Selectivity
Good selectivity provides optimum protection of electrical distribution systems when fault conditions such as overloads, short circuits, earth faults etc. occur. This is essential for the integrity of the system.
