The NSCD rollout has commenced and are being used in a number of areas already across the Region. The first Phases are being used for Network Rail Delivery Unit Isolations with further areas being phased in across the next 4 years. The

use of B4 and NSCDs for isolations will become available for all industry stakeholders and will be mandated across the Southern Region for all planned access requiring isolations where the NSCD are installed. The dates for this will be communicated to you so that you can implemented the appropriate changes within your organisation such that your teams are trained and competent to use the new B4 process and NSCDs.

When we go live the industry must be ready by having their individuals trained and ready to use the equipment. Here you can find out:

Why we are doing this

What an NSCD does

When we plan to go live

Who needs to be trained

How to obtain the competency

Provide electrical protection against inadvertent energisation of an isolated section by an electric train bridging from an adjacent live section

Prevent, via electrical interlocking, against an inadvertent closure of a circuit breaker

Provide electrical protection, in the event of failed interlocking,from the inadvertent closure of a circuit breaker

Provide a methodology of securing an isolation which is demonstrably compliant with the Electricity at Work Regulations

The Southern Region is making isolations safer and faster

by rolling out Negative Short-Circuiting Devices (NSCDs)

and a new isolation process called the B4.

A key aspect of the safer isolations

programme is to install Negative Short-Circuiting Devices

(NSCD) across the dc network.

Strapping

Out

If you are unsure speak to the PICOP or ES

Retain the option of utilising straps under certain restricted circumstances

Frequently asked questionsCan you use straps in a B4?

The B4 isolation process will primarily utilise NSCDs for short-circuiting purposes but retain the option of utilising straps under certain restricted circumstances. Therefore, a combination of NSCDs and short-circuiting straps may be specified on the Form B4.

How would I know that I’m working in

a B4 isolation?

 If you are a COSS or someone working under a COSS then it may not be obvious that you are working in a B4. The ECO/PICOP/ES will know that the isolation is a B4 as they will have a copy of the B4 isolation docket.

How do I find the LCP?

The location of the LCP will be stated on the safe work pack. The LCP will normally be located close to the associated substation or track paralleling hut. If this is not the case the specific location can be found on the Comprehensive Track Diagrams. Signage will be applied to the appropriate access gate to help you locate the LCP

Does this mean I don’t need a

strapping ticket (level B) at all now?

No, you will probably still need to maintain this competency as it is normal during an isolation to have both NSCD and Short Circuit Straps specified on the B Form.

Do I need a safe work pack to

operate an LCP?

Yes, though this could be risk assessed in the future at some sites which are fully fenced and not on or near the line.

Does a NSCD switch off the power?

No. The ECO along with the PICOP open the remotely controllable switches that switch off the affected electrical sections as stated on the B Form. The NSCD is the short circuit protection for an isolation, similar to short circuiting straps.

Performance

Compliance with Electricity at Work Regulations

Faster switching & short-circuiting gives more working time

Additional working time provides opportunity to undertake more work or provide better contingency against overrun

Removes several constraints around S&T testing as the running rails are not used for the short circuiting.

Provides an opportunity for smarter planning of work

Improved performance in the following areas

Reduction in the following areas related to the taking and handing back of isolations
