Building management systems Training systems / trainers for electrical wiring/building management systems: Protective circuitry, protective measures, building mains feed, lighting and intercom systems Industrial wiring, intercoms, alarm systems, hazard alarms and access control KNX/EIB, LON Project work, technical practice, assembly practice systems, planning software ESM protective measures conforming to VDE/EN standards Lucas Nülle GmbH Page 1/10 www.lucas-nuelle.com ESM protective measures conforming to VDE/EN standards The systems for training in protective measures provide ideal support for theoretical and practical instruction, i.e. skills from both these areas are imparted here. Here it is possible to investigate the effects of dangerous conditions, which would be forbidden in practice, without any risks. In addition, the models depict the design and principles of original components and allow for training of important techniques and procedures. The main topics are organised hierarchically, as follows: Standards and terms pertaining to protection technology Network systems (for instance, TN, TT, IT) Protection against lightning and excess voltage Checking electrical appliances after maintenance Carrying out tests on built-in systems Systematic trouble-shooting methods and developing fault finding strategies Evaluation of measurement readings Preparation of measurement reports Lucas Nülle GmbH Page 2/10 www.lucas-nuelle.com ESM 7 Investigation of network symmetry and quality ESM 7 Investigation of network symmetry and quality Use of many electronic appliances, energy saving lamps, uninterruptible power supplies (UPS) and regenerative energies is posing new problems to electricity providers. For this reason it is important to plan the loads on wiring logically and properly. Symmetric loading of mains networks should be one aspect taken into consideration for any wiring installation. In addition, the wide variety of electronic components is causing more and more disturbance to mains symmetry and affecting the quality of the network. This experiment board is intended to convey the key aspects regarding use of switched-mode power supplies, incandescent or energy saving bulbs as they affect mains quality. All the investigations are carried out at mains voltages of 230/400 V and 50 Hz frequency. This ensures that all the results can be reproduced on a real mains network. Training contents: Familiarisation with single-phase and multi-phase systems Relationships between current, voltage and power in coupled systems Ways of depicting coupled systems, e.g. vector diagrams Load on the neutral conductor due to symmetric and asymmetric loads Effects of disturbances on network symmetry Evaluation of network disturbances via network analysis Investigation of neutral loading by the third harmonic Design and effects of various rectifier circuits Lucas Nülle GmbH Page 3/10 www.lucas-nuelle.com Equipment set comprising the following: Pos. Product name Bestell-Nr. 1 Installation board for mains quality and neutral loading CO3209-8L Anz. 1 Non-sinusoidal current consumption by electronic equipment, running up to speed of large electric motors and asymmetric distributions of load or circuitry can result in damaging feedback to the mains network and cause its quality to diminish. Similar symptoms can be seen, though, as a result of self-induced quality problems such as incorrectly sized cabling, non-observation of selectivity features or installation of PEN conductors. In order to detect and evaluate the effects, it is vital to carry out a detailed network analysis by measurement.

Product name Bestell-Nr. 3 Multi-function mains analyser, 8-channel, with graphic capability CO5127-1F Anz. 1 The mains analyser allows for measurement and display of all relevant mains parameters. It is capable of measuring voltage and current for one, two or three phases, along with the neutral, simultaneously. Display and operation are via menu on a liquid crystal display or via the built-in Ethernet port. The “Smart Meter“ operates as a digital electricity meter and measures electricity consumption at the end points of the mains network, as well as being able to turn consumers on and off depending on circumstances.
