Electrical safety verification of machines, portable electrical appliances and switchgear with advanced digital measuring instruments.

Do you develop, manufacture or service electrical appliances, machines or switchgear?Assure electrical safety of your product! Complete selection of test instruments for different applications and environments. Designed to be used in laboratories, workshops, automated production lines and building sites.  Advanced, processor backed-up design enables time-efficient and simple measurements.  Test functions are selected in accordance with the latest IEC/EN or VDE standards requirements.  Windows compatible PC evaluation software for creating test reports. Supported transfer of test results to Excel or Word. All Metrel instruments equipped with AUTO SEQUENCE testing procedure are able to perform several single measurements with one automated procedure. The AUTO SEQUENCE feature can automatically execute all the necessary tests on the basis of predefined appliance type. Besides manual set-up, RFID and BAR code technology can also be used. Metrel instruments provide a PASS/FAIL indication which is displayed after every single test or the AUTO SEQUENCE test. In addition to detailed on-screen test results (displayed on LCD) this function enables further visible evaluation of the result.
AUTO SEQUENCE ® SINGLE FUNCTION TESTS Appliances / Machines / Switchboard Safety Why testing safety of electrical equipment? International / European standardsSafety standardsGeneral appliance testing Primary goal is to use all electrical equipment without danger. Common accidents caused by electrical equipment are:ï‚· Injuries through electric shock caused by malfunctioned equipmentï‚· Injuries through overheated equipmentï‚· Fire and explosionsMost people are not aware that every (even the smallest) piece of EN 60950 Safety of information technology equipmentEN 60335 Safety of household and similar electrical appliancesEN 61010 Safety requirements for electrical equipment for measurement, control, and laboratory EN 60598 Safety of luminaires Electrical machines EN 60204 Safety of machinery - Electrical equipment of machine electrical equipment can cause fatal accidents.Many studies Switchgears EN 60439 Low-voltage switchgear and control gear assemblies h ave proven that the cost and consequences of accidents caused by impaired electrical equipment by far exceed the investments in testing. Of course accidents cannot be excluded completely by regular testing of safety. However they can be limited to an acceptable level.The Test equipment feature standards EN 61557 Electrical safety in low voltage distribution systems up to 1000 V a.c. and 1500 V d.c.- Equipment for testing, measuring or monitoring of protective measures VDE 404 Measuring equipment for testing electrical safety of electrical appliances field of electrical equipment safery is well covered by a series of published standards concerning electrical equipment design, testing instruments and procedures. Standards are important to have a unique testing system worldwide.Testing of electrical equipment is not regulated in the same way in all countries. For instance, in Germany, UK Safety management The term safety management summarizes all the necessary steps that must be taken to assure the safety of electrical equipment through its complete lifetime.These steps are:ï‚· Quality type testing performed by the producer.ï‚· Obtaining an independent certification mark for the product (recommended).ï‚· Strict quality end control at producer.ï‚· Quality maintenance of the product.ï‚· Correct handling of the product according to product manuals and working instructions. ï‚· Frequent visual checks by the user.ï‚· Regular safety check performed by a skilled person (visual check, testing of and Australia a lot of effort was made in recen years to increase the overall electrical safety. In these countries thorough and well documented testing of all electrical equipment during its complete lifetime is regulated by law. Based on their positive experience it can be assumed that other countries will follow them in the future.Testing safety of electrical equipment can be divided safety, “Logbook” of appliance, documentation of tests, etc.).ï‚· Adequate corrective measures in case of a noticed safety problem. with regard to the type of electrical equipment and type of testing. According to the standards electrical equipment is divided in:ï‚· Electrical appliances ï‚· Electrical machinesï‚· Electrical switchgearsTypes of safety tests of electrical equipment safety tests
