FC 5300 Live LV Cable Identifier

The FC5300 is an identifier voltage cable that offers all the information that is needed to distinguish a live LV cable among other cables without risk of error. It involves the identification of cables in open trenches or tunnels, the identification or confirmation of the source and an upstream and downstream cable discrimination at a given point on the network. 

The identifier has a probe with display that guides the user through the steps for every function.

The probe that is extremely sensitive enhances the resolution in cable harnesses. The dependable connectors include double-insulated, sheathed conductors depending on the new standards.

Proving Units

When Clydesdale gave a presentation at the OHLex exhibition in 2016, we discussed the method by which capacitive voltage detectors work correctly when placed inside a steady-state, 50Hz AC (UK lines) electric field above the unit’s configured threshold voltage. A link to this presentation is available here.

 At their core, capacitive voltage detectors need to be placed within a uniform electric field, at a pre-set distance from a live line, in a voltage field level above the detector’s internally programmed “threshold”.
The value for this threshold should be compliant with the International standard IEC 61243-1.
The IEC standard sets upper and lower limits for where this threshold value should be calibrated based on the device’s operating range. This threshold is always stated with respect to the phase-to-phase line voltage.

The IEC standard also makes statements about demonstrating the effectiveness of the device’s “testing element”. A “testing element” is the Built-in or external device, by means of which the functioning of the voltage detector can be checked by the user
The IEC standard describes how it is equally valid to have an onboard or offboard “test element” that is evaluated for performance and reliability as part of the device’s original IEC certification.
No distinction is drawn between the two scenarios. The “testing element” must be able to fully test the operation of the electrical circuits, energy source and any indicators (light / sound).
Onboard test elements do this testing within the devices onboard circuity and systems. Offboard test elements would include, what is more commonly known as, a proving unit.

To be a successful, IEC compliant external testing element any proving unit would need to be:

  • Providing approx. 4kV AC @ 50Hz in a stable field. This is a typical threshold voltage for according to the IEC standard. This is based on a UK specific 11-33kV device as a guide.
  • Providing a mechanical contact for the device’s electrode in an environment free of disturbances to the generated field. This would mean any metallic conductive testing parts need to be laid out in such away so as not to interfere with the required, stable field effect.
  • Produce this voltage field for a reasonable duration to allow the device’s electronics to filter out any noise and identify a successful “live” signal.
  • Provide suitable electrical insulation and interlocks to keep the user safe.
  • Be compliant with the CE directive for Electro Magnetic Compatibility.
  • Portable enough to be used in the field.

 Unfortunately, we do not believe a device that can fulfil this brief exists within the market and so manufacturers of Capacitive voltage detectors have generally moved onto approved internal self-testing of devices.

 As a guide, the Fameca TAG220 and the Fameca Vector from Clydesdale are fully IEC standards compliant and use a built-in, continuous self-test while powered on. The self-test checks every 50 milliseconds for correct operation of the whole electrical circuit, sensors , threshold value and battery level of course.

Extra Mile 2017

Every year Clydesdale puts together a cycling team and enters the Extra Mile Challenge raising money for selected charities.
This year the challenge is set in Brittany on the 21st – 25th September.

The team consisting of David Sample, Simon Raglione-Hall, John Webb and John Wells will start their journey in Chartres,
two nights at Rennes before ending the 500 mile cycle in Normandy at Caen.

The team raise money for BLISS and St Johns Hospice and where able to give the charities over £1100 last year.

BLISS Support premature and sick babies as well as their families

St John’s hospice is a palliative care hospice for cancer sufferers.

 

We wish all the teams involved lots of luck!

CABLEx 2017

The Clydesdale team had a great day at the EA Technology organised exhibition, CABLEx 2017.

The new addition the ‘Demo Den’ was a great success, we had several different demonstrations running throughout the day showcasing new equipment for the UK market as well as some of our core tools.

In terms of cable preparation, demos were given on preparing 33kV graphite coated cables as well as 11kV Triplex cable using the range of Alroc tools.

A non-explosive cable spiking and cutting demo was given using the Picoup 250 tool which is designed to provide a reliable single phase-to-earth fault should the user unfortunately spike a live cable.

Clydesdale also had a custom demonstration table made specifically for the event to show how the FC2310, de-energised cable identifier and phasing device works and how it can be employed in the field.

Our show booklet containing all the products on our stand and in the demo den is available online, please click here.

If you are looking for further information or have any questions on the products, please call 01234 855855 or email sales@clydesdale.net and one of our sales team will be happy to help.

We look forward to seeing you all at next year’s event.

Individual Vehicle Approval (IVA) test for trailers and winches

Did you know it is a requirement in UK law that all new trailers, of any weight, must have either individual or low volume type approval before they are sold to the customer?

What does this mean:
  • Winches and drum trailers are classed as special purpose vehicles and have needed testing since October 2014
  • All trailers must have a unique 17 digit trailer identification number registered with the vehicle inspectorate.
  • All trailers need to pass an inspection that they meet all the road requirements
  • All trailers over 750kg need to have a reverse light and 13 pin electrics
  • It is an offence to sell any new equipment that doesn't meet these requirements
For more information, go to the DVSA's website HERE.

Clydesdale Ltd & Brexit

Clydesdale would like to reassure all of its partners / distributors and end user customers that we will seek to minimise the impact of any of the ongoing changes to UK legislation and its standing within the European Union as far as we possibly can within the realms of our product design, manufacture and supply.

Over the coming months and years there are likely to be changes within the market that affect all UK businesses. Clydesdale commits to ensure that, to the best of our abilities, we shall:

* Keep price changes due to currency fluctuations to a minimum

* Keep our technical certifications maintained until there is a clear, alternative legislative structure in place

* Continually review the developing situation to ensure minimal effect upon our business or yours

* Communicate regularly and clearly when we are aware of changes that need to be made


If you would like to discuss anything related to this or any of the other content of the website, then please call +44 (0) 1234 855855 or email sales@clydesdale.net

Clydesdale Ltd were at OHLEx Overhead Lines Exhibition on the 8th June…….

For us it was a fantastic opportunity to demonstrate our products and was great to see so many people of all backgrounds and areas of expertise showing an interest in our range of products from Overhead Line equipment to our Arc Flash PPE.

Our Technical Manager, Simon Raglione-Hall, gave a presentation on the Correct use of Capacitive Voltage Detector on MV Overhead Lines, which was well received by the audience, details of the presentation is available on request.

The show was, in our opinion, a great success. The team here at Clydesdale Ltd look forward to seeing you all at CablEx next year…
