WHITEBOOK FOR ELECTRICIANS

Product catalog summary
Overview: This document provides comprehensive guidelines for testing and managing electrical installations, focusing on safety, compliance with electrotechnical standards, and the use of specific test instruments and software. It covers initial and periodic testing procedures for low-voltage installations up to 1000 V, electric vehicle charging infrastructure, and various electrical devices.
Testing Intervals:
  • Permanently Installed Equipment: Every 4 years.
  • Special Installations: Annually.
  • Portable Equipment: Every 6 months, with potential extension based on fault rate.
  • Construction Site Equipment: Every 3 months, with potential extension based on fault rate.
  • Earth-Moving and Construction Machines: Annually.
  • Industrial Trucks and Platform Lifts: Annually.
Testing Procedures:
  • Visual Inspection: Checking for correct equipment selection, damage, protection against direct contact, and proper labeling.
  • Functional Testing: Ensures correct operation of safety and monitoring devices, power installations, and bus systems.
  • Measurement: Involves continuity, insulation resistance, voltage polarity, and phase sequence tests.
Documentation: Detailed test reports are required, including visual inspection results and measurement data. Reports should be understandable to non-specialists.
Standards and Compliance: Testing instruments must comply with DIN EN 61557 standards. Documentation requirements emphasize the need for clear and comprehensive reporting.
Practical Tips: A checklist for periodic testing includes system condition assessment, technical documentation verification, ambient condition evaluation, and test requirement determination.
Insulation Resistance: Insulation measurement must be conducted between all conductors and the protective earth (PE) at the supply point. Measurements should be performed with direct voltage, and the measuring instrument must display insulation resistance according to specified limit values.
Initial and Periodic Testing Procedures: Testing should be done in a voltage-free state, and insulation measurement is only performed in areas where measurement voltage is applied. Capacitive power consumers must be discharged after measurement.
Insulation Monitoring Devices (IMDs) and Residual Current Monitoring Devices (RCMs): IMDs are used in IT systems to monitor minimum insulation resistance values. RCMs monitor residual current and can control external switching devices to shut down power if necessary.
Automatic Shutdown in Case of Error: Earthing resistance must be measured, and short-circuit triggering is determined by fault loop impedance. Protective devices must ensure shutdown within specified time periods according to IEC 60364-4-41.
Residual Current Device (RCD) Testing: RCDs must trip no later than upon reaching their rated fault current value. Testing involves measuring touch voltage at electrical outlets and ensuring no premature tripping occurs.
Specifications and Standards: The document outlines specifications for initial and periodic testing in low-voltage installations up to 1000 V, referencing standards such as DIN VDE 0100-600 and IEC 60364-6.
Testing Instruments: Describes various testing instruments, including the PROFITEST series and GEOHM series, highlighting their capabilities such as loop and line impedance measurement, insulation resistance measurement, and earth resistance measurement.
Software and Data Management: Software solutions for test instruments are discussed, including ETC and PC.doc for report generation and data management. The document highlights the integration of these tools with Microsoft Office applications for comprehensive facility management and documentation.
Electric Vehicle Charging Infrastructure: Initial and periodic testing must be conducted by qualified electricians, including visual inspection, measurement, and documentation. Tests ensure compliance with IEC and EN standards.
Harmonics and Power Quality: The document discusses the impact of harmonics and sub-harmonics on electrical systems, highlighting issues such as increased losses and equipment malfunction. It provides solutions for mitigating these effects.
Technical Safety Inspection Requirements: Only qualified individuals with appropriate training, knowledge, and experience can conduct technical safety inspections. They must be independent and have access to suitable measuring and test equipment.
Testing of Medical and Electrical Devices: The document specifies the measurement of device leakage current, insulation resistance, and touch current for electrical medical devices, emphasizing compliance with IEC EN 62353.
METRAHIT Series Multimeters: The document provides detailed specifications and features of the METRAHIT series of digital multimeters, designed for measuring electrical quantities with high accuracy and safety.

WHITEBOOK FOR ELECTRICIANS-2

Our test instruments are manufactured in accordance with the state-of-the-art and comply with the requirements of German occupational safety law concerning the provision of safe work equipment. Equipment should nevertheless be tested at regular intervals for safe condition in accordance with German occupational safety law (BetrSichV) and TRBS1201. Measuring functions should also be tested at regular intervals because reproducibility of measurement results is required by the inspector. Our company is accredited to do this. Our service center would be happy to provide you with quotations for your...

WHITEBOOK FOR ELECTRICIANS-9

Initial and Periodic Testing in Low-Voltage Installations with up to 1000 V The state of the art is defined in the officially recognized technical rules (TRBSn, ASRn, TRGS). Legally, trade association rules and regulations are based on the German code of social law, VII (§15), and to a great extent have already been superseded by German occupational safety law, subsequent ordinances and state technical rules, which have precedence. As opposed to DGUV rules, state technical rules demonstrate presumption of conformity when applied. This little whitebook is intended to provide you with support in...
