Further development of the integrated voltage detecting systems

The Wega series according to the IEC 62271-213 standard ensures maximum operational safety for network personnel

Is voltage present or absent? This question is fundamental, and a precise answer is essential when service or maintenance personnel are working on switchgear and cables. The integrated voltage detecting systems, such as the Wega series, are either factory  installed in switchgear or can be retrofitted. Due to the built-in internal  monitoring, maintenance testing is not necessary and the Wega series is therefore maintenance-free.

Horstmann has further developed its proven Wega series for the new international VDIS standard IEC 62271-213 (VDIS - Voltage Detecting and Indicating System) in order to comply with the new requirements.

The new Wega series permanently tests for your safety and reliably determines the voltage status in accordance with IEC 62271-213 in medium-voltage switchgear.

It has the same electrical properties as the previous Wega series, which  can be easily switched over to the new Wega VDIS series. The proven quality and durability of this safety-relevant product has of course been maintained and is ensured, a.o., by the complete encapsulation of the electronics.

Optimised functional details of the Wega series in accordance to IEC 62271-213

In addition to the adaptation of the new standard, the handling has also been optimised. In particular, the new tool-free installation, which was developed at customers' requests, should be mentioned here. This offers major time and cost benefits, particularly in series production. The extended temperature range of -40°C to +75°C facilitates worldwide use. Thanks to optimised connections, all connecting cables to the Horstmann directional fault indicators are now equipped with an AMP connector for each switchgear. The connection of the capacitive tap, on the other hand, can still be carried out with AMP plugs or flat plugs by the switchgear manufacturer.

Wega 1 and Wega 1 V are three-phase voltage detecting systems that display medium-voltage states. The display test function built into the front allows the display to be tested in the installed and voltage-free state. Shielded and unshielded cables with flat plugs or system plugs can be connected.

New features:

• Bracket for tool-free installation
• 2 connection options (AMP/flat plug) - Can be used universally for all medium-voltage switchgear
• Optimised display contrast, extended temperature range and display test
• Safe voltage transfer to the directional  fault indicator (AMP OUT)

Wega 2 and Wega 2 V have the same range of functions as Wega 1 and Wega 1 V, but also have two additional LED indicators (green U=0 and red U≠0) on the front. The voltage status of the system field can be signalled remotely or used for interlocking purposes via two independent relay contacts.

Further development of Vario versions

The Wega Vario has also been further developed and now contains 15 adjustable capacitance values that can be very easily set phase-selectively using integrated rotary switches. Horstmann is thus launching a particularly user-friendly and quickly adjustable product onto the market.

A completely new version of the Vario family is the Wega 2 V, which combines the Vario function with relay outputs for remote signalling and was previously not available in this form factor.

Product features of the Wega series:

• Quality: Made in Germany - fulfils the highest quality standards
• Tool-free installation - Saves time
• Integrated maintenance test - Maintenance-free
• Fully encapsulated electronics - High functional reliability
• -40°C to +75°C - Extended temperature range
• High display contrast - Improved readability
• Safe voltage coupling of ComPass and Sigma D series - Retrofit ready
• Vario: Phase-selective rotary switches - Quick and easy commissioning
• LRM interface on the front - Fully compliant with IEC 62271-213
• Wega 2: Integrated current-carrying relay contacts - Reliable remote signalling of voltage states

In conclusion, it can be said that Horstmann produces high-quality products that have no equal. Everything starts with the development and design at our headquarter in Heiligenhaus. From the printed circuit board through the housing to the encapsulation, the focus is on quality and precision "Made in Germany". Our customers benefit not only from outstanding German craftsmanship, but also from an efficient supply chain. The usual delivery time is only 2-3 weeks. Thanks to our good inventory levels and flexible production, partial deliveries of larger quantities are also possible at short notice. This flexibility is one of our strengths and contributes to our well-known reliability. 

Summary

Personnel safety is our top priority. In order to be among the best in the world when it comes to voltage testing and monitoring systems in medium-voltage networks, we develop and produce future-proof products that are above all easy to use. The new Wega series from Horstmann, in accordance with the international VDIS standard IEC 62271-213, is an advanced solution for permanently monitoring the voltage status in medium-voltage switchgear. The Wega 1 and Wega 2 models are three-phase voltage detecting systems with optimised functional details, improved connection options and an extended temperature application range. The Wega Vario variants have been further developed and now enable phase-selective settings for up to 15 adjustable capacitance values. A new variant, the Wega 2 V, combines the Vario function with relay outputs for remote signalling. All products in the Wega series are characterised by "Made in Germany" quality, tool-free installation, integrated repeat testing and fully encapsulated electronics. Horstmann also offers short delivery times.
