? Metrel newsletter NEW video: fire engine testing with MI 3309 BT DeltaGT ? We have prepared a new instructional video for MI 3309 BT DeltaGT depicting its use for testing electrical safety of extension cord reels that are a part of fire engine's inventory and used by firemen during their work. This includes tester (instrument) preparation, connection to an extension cord reel and entire testing procedure with a walk through the menus ending with comparison of test results with prescribed limit values. ? You can view the video by clicking on the image on the left. More about MI 3309 BT DeltaGT Metrel d.d.

Metrel newsletter NEW product: A 1722 PRCD adapter ? We have launched another new accessory: A 1722 PRCD adapter, designed for functional and electrical safety testing of single and three-phase portable residual current devices (PRCDs). It supports simulation of different error states and has connection inputs for testing of PE wire (if monitored by PRCD). Among supported tests is also the probe test (to test PRCD''s touch electrode) in addition to other standard tests for PRCD testing. Supported functional testing of the following PRCD types: PRCD-S (1-phase / 3-pole and 3-phase / 5-pole) PRCD-S+ (1-phase / 3-pole) PRCD-K/Di (1-phase) PRCD (2-pole and 3-pole) Supported fault simulations (for functional testing): L-open (for 3-phase L1-L3) N-open PE-open Reversed wires (for 1-phase L <> PE / L <> N, for 3-phase L1,L2,L3 <> PE / L1,L2,L3 <> N) External voltage on PE Other supported tests and measurements include: Measurement of protective conductor Measurement of insulation resistance Measurement of PE-current with optional current clamps Tripping test Probe test The A 1722 PRCD adapter is supported by the following instruments: MI 3155 EurotestXD MI 3152 EurotestXC MI 3152H EurotestXC 2.5kV More about A 1722 PRCD adapter Metrel d.d.

? Metrel newsletter VIDEO: MI 3155 EurotestXD & A 1507 3-Phase Active Switch ? Testing 3-phase electrical installations can be arduous, but only if not done with our A 1507 3-Phase Active Switch as depicted in the video down below (testing the correct phase sequence on a 3-phase socket). ? The video likewise depicts using the aforementioned combination for testing phase sequence the origin of the (3-phase) electrical installation. The A 1507 3-Phase Active Switch can also be used with MI 3152 EurotestXC or MI 3152H EurotestXC 2,5 kV and supports a number of other measurement/testing functionalities, including: Voltage Continuity of protective conductor Resistance N-PE Insulation resistances Resistance to earth Line and Loop impedances RCD testing More about MI 3155 EurotestXD More about A 1507 3-Phase Active Switch Metrel d.d.

Metrel newsletter P-RCD testing with MI 3360 OmegaGT XA ? Electrical safety in all shapes and forms, particularly electrical appliance safety, is a growing concern and rightfully so. Electrical appliances and tools are becoming increasingly complex and may be used by some users in an unsafe manner, necessitating additional safety mechanism apart from those integrated in said devices. One such preventive measure is the use of portable-residual current protective devices (P-RCDs) with a rated residual current I ?n ? 30 mA. The P-RCDs need to fulfil the following requirements:                Rated differential current I?n ? 30 mA. Has to switch all poles, including the PE conductor. Undervoltage release. Must not restart after the voltage returns. Must not to switch on if the PE conductor is interrupted or energized. If voltage is detected on the PE conductor or if the protective conductor is interrupted during operation the RCD must switch off. PE conductor must not be switched off if external voltage is detected on the PE conductor. Each and every of the aforementioned functionalities and features needs to be tested, requiring a structured approach encompassing both safety and functional tests. Few technological solutions on the market support this, except MI 3360 OmegaGT XA. The MI 3360 OmegaGT XA supports testing of the following types of P-RCDs: 2-pole. 3-pole. K/Di (varistor). S (3-pole). S+. Additionally, tests can be executed manually via selection of single tests or automatically with the help of integrated AutoSequence?s. More about MI 3360 OmegaGT XA Metrel d.d.
