Voltage Testing Systems

Product catalog summary
Overview: The document discusses the DRIESCHER voltage testing system for medium voltage switchgears with rated voltages of 12 kV, 24 kV, 36 kV, and 38.5 kV. It emphasizes the system's role in ensuring safety and compliance with new standards, especially in metal-enclosed switchgear systems.
Specifications: The system complies with European standard EN 61243-5 and international standard IEC 61243-5. It includes components like coupling capacitors, voltage limiting rupture joints, and measuring points, designed to operate under both low and rated voltage conditions.
Components: Key components include a high voltage capacitor coupling electrode to prevent external leakage fields and a divider insulator integrating the coupling capacitor. The interface module is tailored for 3-phase AC systems, ensuring clear voltage indication.
Technical Data: Detailed specifications cover mechanical strength, operating temperature, and coupling capacity, along with dimensions and weights of various insulator types.
Testing and Compliance: The system has undergone high-voltage laboratory testing to meet regulatory standards, including saline fog tests for insulation resistance under adverse conditions, as specified in VDE 0682 Part 415.
Display Units: DEHNcap display units are available for testing voltage-free and in-phase conditions, featuring passive and active units with self-testing devices and battery monitoring for clear voltage presence indication.
Phase Comparator: The DEHNcap/PC phase comparator tests in-phase conditions, offering automatic disconnection and visual phase angle displays.
Recommendations: The document advises using the voltage testing system for safety in medium voltage switchgears, particularly in metal-enclosed environments, stressing compliance with the latest standards to prevent electrical accidents.
Product Overview: Details are provided for a voltage testing system for rated voltages over 1 kV, identified by article number 2-33703065, part of the LRM series, including HR-LRM, LR-LRM, and XC-LRM variations.
Specifications: The product is compact and lightweight, weighing approximately 0.250 kg with dimensions of 145 mm x 85 mm x 32 mm, suitable for various testing environments.
Ordering Information: An order number, 3-81707131, is provided for procurement or further inquiries.

Testing the off-load condition and phase comparisonon medium-voltage switchgears is gradually becoming a problem, based on their increase in use. Voltage testing systems have therefore been introdu- ced to meet all safety requirements in such systems.In VDE 0682 Part 415 (IEC 61243-5) the minimumrequirements and testing conditions are specified for capacitive voltage testing systems. Our product program for capacitive voltage testing systems comprises: Response voltage, clear display In order to achieve a clear indication, the couplingparts must be designed in such a way that at a phase-to-earth...

Nominal voltage and rated voltage Coupling elements as defined in VDE 0682 Part 415(IEC 61243-5) are preferably installed in medium-vol- tage switchgears in compliance with DIN VDE 0670 Part 6. The voltage specification is, however, diffe- rent in both standards.In the VDE 0682 Part 415 (IEC 61243-5) for capaci-tor voltage testing systems the voltage is defined as nominal voltage and in DIN VDE 0670 Part 6 for medium-voltage switchgears the voltage is defined as rated voltage (refer to table).VDE 0682 Part 415 (IEC 61243-5) Nominal voltage in kV6102030DIN VDE 0670 Part 6Rated voltage in kV7.2122436...
