Demonstration boards LV
Equipment for Laboratories and Schools
Teaching and training new generations of electricians, electrical engineers and electrical safety inspectors can be a tall order without the proper teaching materials and didactic tools. Design and production of the latter also falls within Metrel’s mission of providing technical solutions for electrical safety testing. We offer a number of dedicated demonstration boards, for training in safety testing of PV and domestic installations, portable appliances (PAT) and much more, including a large aptly named “training corner” that offers a complete training suite.
Features*
- Safety first: training with electronic protection circuits monitoring possible dangerous situations.
- Simulation of trip-lock or unexpected tripping-out of building’s installation circuit protection.
- Simulation of good or bad conditions: pass and fail barriers settings on all decision making parameters.
- Ideal tools for training inspectors, maintainers, installers or any other decision makers.
- Modules are supported with handbooks, posters, charts, presentations, exercises, catalogues of knowledge and catalogues of exams plus approved certificates (optionally when separate training module is localized).
