Mersen Medium Voltage IEEE Fuses

Medium voltage controllable fuses are a modern innovation providing a cost-effective solution to mitigate the Arc-Flash hazard to the low-voltage side of a medium voltage transformer.

How does the Intelligent Fuse System Work?

The Mersen A155CNF Series operates like a normal MV fuse under short circuit and overload situations. When connected to an Arc-Flash detection system that is properly set up, the MVCF will open the circuit in time to limit the Hazard to Category 2 PPE. The Mersen MVCF System’s Interface Module (CFIM) is mounted in the Low Voltage area and accepts a trip signal from the customer’s existing Arc-Flash detection relay. The CFIM immediately sends a signal over fiber-optic cables to the Actuator Modules (CFAM) attached to the bottoms of the fuses in the Medium Voltage cabinet. The CFAM then causes a switch within the fuse to open. This shunts the current through a much smaller fuse element that opens the circuit in a controlled manner.

Features:

-          Fuses fit into existing clips and space – The retrofit can be completed in minutes, provided fiber optic cable is already in place.

-          Lowest-cost Arc-Flash Mitigation Solution – A turnkey installation of the MVCF will cost a fraction of other available alternatives

-          Exceptional Performance - 50kA short circuit interrupt rating

-          Fast response time mitigates the arc-flash energy to Category 2 PPE

-          Low Maintenance – Fuses are designed to last 20 years with no maintenance intervals, and the battery lasts for 3 years

-          Flexible Design Interface – Designed to be used with a variety of conventional Arc-Flash detection devices and relays

-          Minimal stress on other devices – The fuse element softens the voltage spike that occurs when opening. Alternatives may generate an excessive spike that could damage transformer insulation or upstream devices

-          Small Back-up Power Cells – The MVCF utilizes small batteries that fit inside the Controllable Fuse Actuator Module (CFAM) versus other solutions requiring multiple lead-acid car batteries

CaGBC Zero Carbon

The Canada Green Building Council (CaGBC) has taken a major step toward helping Canada achieve its climate change commitments with the launch of the country’s first Zero Carbon Building Standard.

 

This highly-anticipated standard assesses carbon use in commercial, institutional and multi-family buildings in Canada. To achieve large-scale market transformation, it was designed to be broadly applicable for many types of new and existing buildings.

Low-Voltage TrendsThe shift from electrical to digital systems, and the emerging low-voltage power options to supply them, may be the biggest change the electrical industry has seen in the last 100 years. This transition is having significant impact on every aspect of the traditional electrical channel, from product conception, production, sales, delivery and installation.Equipping the channel to embrace emerging technologies, specifically those related to low-voltage direct current (LVDC) power developments,* and opportunities derived from LVDC systems, is the purpose of this research study by Electro-Federation Canada.
