INDUSTRY UPDATES


These OBSOLETE Items may be in your Data Center

​ 

Woodward DSLC-MLSC and GE 90-30 PLCs
 
GE has recently announced that its 90-30 programmable logic controller (PLC) will be discontinued in the fall of 2017.  According to a recent GE newsletter addressed to all customers, This  90-30 PLC has been in production for nearly 30 years and has an installed base of 700,000.
 
In the data center industry, these PLCs have long been the workhorse of many generator and switchgear automation schemes.
 
The 90-30 PLC was moved from “active” to “Mature” status last fall. GE will continue to sell these until they are discontinued in 2017.  The RX3i is the next generation of this technology and it has been in the marketplace for over 5 years
.

The Woodward DSLC-MSLC product used for synchronizing and soft loading has been discontinued however spare units are available today and repairs will be supported through 2020.

 If you have these products in your facility, we recommend the following: 
  • Review your spare parts inventory to confirm whether you have attic stock.
  • If not, contact your generator and switchgear service provider and purchase spare units.
  • Or alternatively, consider updating to the RX3i or and DSLC-MSLC-2.   
If you choose to upgrade  to the latest controller, a rigorous commissioning initiative will be needed to verify the operational integrity of switchgear power transfers, soft loading and engine-generator operation.
Are you prepared for Solar Flares?

​ ​ 
According to industry experts and several real-world occurrences, Geomagnetic Induced Currents (GIC) injected into transmission lines by solar flares will continue to threaten the global electric grid.  
 
A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with a sunspot.  Solar storms can last from minutes to hours and the most notable event occurred in 1989 and caused a 9-hour blackout for over 6 million people served by Ontario-Quebec power company.
 
Electric utilities are now using geosynchronous satellites that can provide up to 15 minutes of notice of an arriving magnetic pulse that accompanies a solar flare.  
 
This may eventually lead to an early warning system used to alert operators of data centers and enable them to switch to backup power much like the lightning alert systems used today.
 
Recent research indicates that core form and shell form power transformers can be susceptible to overheating and failure from high levels of GIC.
 
Most of the service transformers in North America used to power buildings are oil filled pad-mounts of the core form design.
 
We recommend the following to harden your site against solar weather events:
  • Invest in backup power that is grid-isolated
  • Procure spare service transformer(s)
  • Test the backup power system on a regular basis
