Jornada técnica sobre el estudio de selectividades y protección de arco interno en los cuadros CCMs

 

 
Tuvo lugar el pasado miércoles 28 de mayo en el Colegio Oficial de Ingenieros Técnicos Industriales de Valladolid con gran éxito de convocatoria.
 

La seguridad en las instalaciones eléctricas de baja tensión ha ido cobrando una creciente importancia. Es imprescindible anteponer la seguridad a cualquier otro requisito en una instalación eléctrica y realizar una selección adecuada de las protecciones a instalar durante su fase de diseño, de modo que ante un fallo, éste quede aislado sin interrumpir el suministro eléctrico en el resto de la instalación.

 
En esta jornada se ofreció a los asistentes información técnica sobre el diseño de la instalación en cuanto a selectividad y filiación, proporcionando una herramienta informática, así como información técnica acerca del arco interno y de los cuadros de centros de control de motor (CCM).

   New Pro-DB Distribution Board and Pro-Panel Panelboards

Terasaki’s new distribution equipment meets the needs of modern commercial and industrial building electrical installations. Complying with UK regulations and standards for building projects*. The range includes Distribution Boards, Panel Boards and Integrated Metering Solutions.

New TP&N Offer

Pro-DB Type B distribution boards are fully type tested with a conditional short circuit rating of 25kA to BS EN 60439. Variations for the 125A TPN board include a choice of: 4, 6, 8, 12, 18 and 24 TP outgoing ways. For applications where the number of MCB ways requires a larger supply current, a 250A rated TPN version is also available in 8, 12, 16, 18 and 24 outgoing ways.

Complementing the Pro-DB distribution board is a completely new range of TD3 MCBS and single module RCBOs, providing the highest levels of safety and performance required for your installation. Assuring our customers that they are buying a component of good quality

Facilitating various industrial and commercial distribution applications, the choice of incomer options include: Switch Disconnectors, MCCBs, RCCBs and Contactor incomers. The TP&N distribution board can easily be converted to a SP&N system by utilising a single phasing kit for both 125A and 250A ratings.

Compact Solution for Energy Metering

Integrated metering can be easily achieved by simply adding a meter next to the incoming device in the 125A & 250A board. This means that simple energy meters (kWh) with pulsed output, digital multifunction meters with pulsed output or digital multifunction meters with Modbus output can be installed inside the board without the need for an extension box.

Split metering of lighting and power loads in the distribution board enables compliance with the building regulations in the UK. Pro-DB TP&N boards can separately monitor lighting and power loads by utilising dual metering kits in horizontal board configurations. Separate metering facility for a 125A board is also available in a vertical board configuration.

With generous wiring space and a unique cable entry system, why not switch over to the Pro-DB distribution range? Contact marketing@terasaki.co.uk for our Pro-DB price list and product brochure.

   Terasaki and Mardix Pass Test at One Hundred Thousand Amps

Terasaki and Mardix are delighted to announce the success of their joint switchgear testing program. Engineers at Mardix have designed a new industry-leading, high-capacity distribution switchgear system incorporating Terasaki circuit breakers. Intended for use in buildings with high, concentrated electrical energy demand such as data centres and banks, it has now been proven to withstand short-circuit fault current of up to one hundred thousand amps (100kA).



Peace of Mind from Independent Testing and Certification to IEC 61439

The consequences of switchgear failure when a business depends heavily on the availability of electricity could be disastrous. Terasaki and Mardix had the system independently tested and certified to give users and specifiers peace of mind about the performance of the equipment.

Short-circuit performance at 100kA was tested at the ASTA-approved DAMSTRA laboratory in the Netherlands.

Temperature performance was verified at kA Testing in the UK (also ASTA-certified). This highlighted the superior thermal performance of the switchboard and circuit breakers in that:

    
• a rating of 6300A for the incoming circuit (a TemPower 2 ACB) was achieved with natural cooling;

     • Outgoing circuits rated from 160A to 3200A (TemBreak 2 MCCBs and TemPower 2 ACBs) achieved a diversity factor of         1 with natural cooling.

Latest Switchgear Standard

The system was designed and tested to the latest standard for low-voltage switchgear assemblies, IEC 61439. ASTA certificates are available and reference the new standard.

Collaboration Offers Choice to Clients

Terasaki and Mardix are independent companies, successful in their separate, but overlapping business areas. Terasaki are the UK’s foremost circuit breaker specialists, supplying components to switchboard builders for a wide range of commercial, industrial and marine projects. Mardix deliver an integrated solution for every aspect of the critical power life cycle through switchgear, power management and service.
The co-operation between Terasaki and Mardix offers choice to clients who like to select the best technical solution for a project without being restricted to using the same brand for systems and circuit breakers due to existing certification. Some examples of the benefits of this “best of breed” approach are:

     • Reduction in space required for switchgear in the building. 100kA short-circuit withstand ratings can achieved in         1400mm wide incoming switchgear compartments. This is possible only due to the unique combination of Air Circuit         Breakers with exceptional ratings (Terasaki) and busbar design (Mardix) and can result in space savings of up to 40%         over conventional designs.

     • Overheating is the single most common cause of failure in switchgear. Full critical power monitoring systems,         incorporating real-time, continuous thermal measurement of circuit breakers is an easily achieved option with this         combination of equipment.

   TERASAKI Circuit Breakers Type-Tested With CUBIC

Two independent and innovative switchgear companies have co-operated to conduct a successful type-testing programme.

Terasaki and CUBIC are independent and innovative companies who have co-operated to offer one of the world’s most compact switchboards certified at up to 100kA - Icw for one second, containing Terasaki circuit breakers from 12A to 6300A.

We have proven the performance of our products together with a test programme, certified by KEMA and ASTA, at fault levels of 65kA, 80kA and 100kA.

This delivers unsurpassed circuit protection with built-in reliability and safety, giving confidence for the future of energy distribution.

Tests conducted:
   • Temperature rise
   • Dielectric properties
   • Short-circuit withstand strength
   • Effectiveness of the protective circuit
   • Creepage and clearance
   • Mechanical operation
   • Degree of protection
   • EMC
   • Resistance of insulation materials
   • Partial test to IEC 61439-1,-2
   • Internal arc fault containment to AS3439-1
Annex ZD and AS3000

Terasaki products included in this testing;

Moulded Case Circuit Breakers (MCCBs) - TemBreak2

One of the most powerful features of the TemBreak2 MCCB is that it is so easy to install and operate - it was designed that way.
TemBreak2 MCCBs are now available with high tech integrated LCD energy monitor which can be connected to an Automatic Monitoring and Targeting system.

The TemPower 2 ACB is extremely reliable in service.
All models in the range have a short-time withstand rating equal to their service breaking capacity. This guarantees total discrimination without further calculation because it allows short-circuit protection to be time-delayed even at the maximum prospective short-circuit current.
