Busbar Technology  |  Automation – PLCs  |  Energy Management

Busbar Technology

Busbars are the main electrical conductors in a control panel that supply current to all consumers in the cabinet. The traditional
busbar technology is beset with problems like large size, inconsistent material, connections through holes and fasteners, slow
and      labor-intensive assembly process, metal corrosions and similar. With an open execution, traditional busbars are also inherently unsafe to the people working in the control panel.

Traditional busbars did not have competition, until Wöhner® busbars became available. With their cohesive and modular approach, Wöhner®busbar systems offer outstanding advantages over their traditional equivalents.

Benefits of Busbar Technology

• Compliance with IEC 61439 and UL 508 standards including IP20 touch-safe protection.
• Small size of busbar with close stacking pitch, resulting in significant reduction of panel dimensions.
• Inherent safety due to touch-safe, all-around covered construction.
• Direct mounting on DIN rails, without use of external busbar supports.
• Speed of installation, the busbars and their connected components can be installed and wired without any drilling, tapping, or crimping of lugs.
• Clamp-on connections ensures that busbar is not drilled and there is no loss of metal mass.
• Simplicity and convenience with snap-fitting and clamping of parts
• Ease of expansion by stacking other busbar modules
• Compatibility with all standard switchgear that directly mount on the busbar.
• Adaptability with various Wöhner® supplied functional modules that mount directly on the busbars.
• Long, corrosion-free life.
• Free online utilities to help busbar user:
  • Configure the busbar selection and design.
  • Calculate the current metal surcharge.
  • Verify design as per IEC 61439 standards.
  • Calculate current carrying capacity, thermal derating, and short-circuit capability of busbars.
  • Shortlist the adaptor and connector types.
• The reports generated from online utilities can certify compliance to mandatory IEC 61439 and UL 508 standards without requiring expensive consultancy, or laboratory tests.

Wide variety in Busbar Technology

• CrossBoard®: 3 pole covered busbar system for 3 phase loads up to 125 Amperes.
• 30 Compact®: 3 pole and 5 pole covered busbar systems for 3 phase loads up to 360 Amperes.

• Panel accessories: Large selection of connectors, covers, adapters, laminated and flexible busbars, and more.

Energy Management Solutions

Smart Panel for Power Measurement

This smart panel monitors, records, and controls electrical energy for a large installation. This system integrates intelligent energy meters, energy analyzers with PLCs to measure energy, and implement control using interlocks and time
schedules. This logic could be based on load and consumption algorithms for that respective industry or infrastructure.

These solutions meet IEC 61439 standards for PLCs, SCADA (Supervisory control and data acquisition) and IoT (Internet of things) based technology. The energy meters used in the setup have a variety of communication modes and can
directly connect with PLCs, SCADA or customized applications with the minimum of wiring.

The smart panel can monitor and analyze data as per a section, like the department, or the load, or the area. This segregation helps you understand the tariff allocation as per zones, to result in reduction in overall energy
consumption, and the billing. Historical data is stored for analysis and trends either locally on a server or on the cloud, for universal access from anywhere.

These smart panels map peak demand times and automatically regulate loads as per priority to avoid exceeding the sanctioned capacity. To
ease current sensing on continuous duty, high power circuits, Messung offers advanced technology clip-on sensors that avoid shutting down the line for inserting measurement CTs (current transformers).

Benefits of Smart Panel for Power Measurement

• Helps reduce energy consumption
• Improve utilization of the system
• Increase reliability
• Predicts electrical system performance
• Optimize energy usage

This panel is integrated with IOT based solutions, to deliver data to a remote internet connected computer or mobile phone. This remote delivery of the data shows readings, and alarms to get quick and effective response from the user,
who may be away from the plant. The stored data helps in analytics and trend prediction.

Clean Power Solution

This solution aims to offer clean power to critical loads. The solution uses energy analyzers, active harmonic filter, surge protection and similar devices to filter unwanted noise and harmonics from the incoming lines.

These turnkey solutions can also offer an intelligent control on varying power factor with capacitor banks. This panel supplies clean power supply with a near unity power factor to minimize the tariff charged by the utility providers.

Typical application of clean power is for high value critical equipment such as quality control machines, laboratory equipment, medical equipment, and data centers. Apart from the utility grid input, the clean power solution can also
monitor the alternative sources of energy such as UPS (uninterrupted power supply) and diesel generating set.

By adding a PLC, these solutions can activate various interlocks and switch loads to provide clean power and avoid running non-critical loads during power outages. This solution also has an IoT interface to extend the readings, and
alarms to remote computers or mobile phones over the internet.

This panel connects to various power inputs and supplies power to load as per the priority.

Using a PLC for taking decision about selection of sources and connected load, this smart panel meets IEC 61439 standards for safety of power distribution.

Messung’s SPDS is useful for buildings like villas, bungalows, farmhouses, hospitals, hotels, commercial complexes and similar that have multiple sources of power input like mains, UPS, diesel generating set and, renewable energy sources (wind, solar).

The SPDS connects the critical and non-critical loads with the available power source as per a variety of factors. This intelligence helps to maximize the use or renewable energy and ensure that critical load are always powered-up. The exact algorithm for optimal use of energy is customized as per the site requirement.

The panel includes intelligent monitoring for the entire electrical system of the building, management of solar energy and its battery, IoT interface, cloud connectivity, and easy integration with a variety of home automation systems like KNX, Crestron, and similar.
