EES is a family owned mid-sized company, combining technological expertise and innovation since more than 40 years.
We are providing high-value solutions in the range of fault annunciating and telecontrol systems. Today we are contributing with a comprehensive lineup to increase availability and operation reliability of countless energy generation and distribution plants all over the world.
The latest product generation covers todays and future requirements in the field of substation automation with IEC 61850 and offers also links to superior SCADA Systems over IEC 60870-5-104.
Our products are based on recognized market standards. Adaption to process parameters onsite can easily be done e.g. by integrated Web-Server. Reliable signal transmission on various media is also a core competence of EES.
Furthermore we secure the long-term availability of spare parts for our products. EES is certified by Dekra Corporation to comply with DIN EN ISO 9001:2008 and 14001:2004 standards.
EES offers products in the field of switchgear monitoring and fault annunciating ranging from simple devices with predefined settings up to a networkable systems with IEC 61850 and IEC 60870-5-104 multilink structures.
Setting into operation and adjusting to parameters on site, DIP switches and easy of use browser based software are provided. Hereby standardized reporting procedures acc. to DIN 19235 or ISA, as well as individual sequences can be realized. Drop flap functionality suits the demand for displaying last states of a facility. Supervision relays monitor voltagelevels, as well as phase failures in networks.
Moreover EES multiplexer systems convince by universal applicability, simple handling and low installation costs. The systems are compact and have high interference resistance for transmission of digital and analog I/O’s up to 20 Kilometers over arbitrary control lines or wireless.
For reliable transmission and evaluation of the data telegrams secured protocols are used.
The WAP is the most advanced windows annunciator panel ever designed. In contrast to the mechanical adaption of windows sizes, this device delivers the easy setting up of windows by drag and drop via browser. Each window can be fully adapted in terms of width and height and colour. Repeat relays for each input, 3 common alarms and redundant power supply are available. For connection to IEC 61850, Ethernet or optical fibre sockets are provided and several devices can be connected via CAN-Bus.
The small transceiver and receiver unit ZS8A stands for its reliability and rigidity against interferences and is commonly used for carrying field signals over a long distance control cable to superior RTUs. Moreover these devices find their home in control of cradles in building maintenance applications.
Easy setting up with DIP-switches and small housing makes it easy to integrate in existing cabinets. For higher demands EES provides the appropriate systems, too.
The basic fault annunciating family for switchgear panels. The functionality and the modular design of the devices with up to 48/192 inputs and corresponding output relays offer flexibility through individual processing for single signals and also for alarm- and operation states. Collective reports and repeat relays provide flexibility in alarm notification. Very bright two colour LEDs provide a very large reading angle. Parameterisation can be changed by buttons or via webinterface.
EES offers a large variety of telecontrol systems to transmit data over large distances about 10km or more. In particular wireless transmission over registration and free of charge use radio bands is a EES USP.
To secure the data transmission between each station, an AES based encryption can be activated. This symmetric process is executed by a pre-shared key, which can be generated dynamically by the parameterization software and can be different for each station.
Moreover a relaying of data can be carried out over each station, in case a line of sight is not available. By this analog and digital values as well as serial and IP based Modbus data can be exchanged reliably by this technique.
