1.6 CDCA Obligation

In the event of any fault or failure of a communication link (or any error, or omission, in metered data, or all necessary data not being available from Outstations), and where the CDCA needs to break a Metering Equipment seal(s) in order to perform manual on-site interrogation of the Outstation(s), the CDCA shall:

Reseal the Metering Equipment immediately following the manual on-site interrogation of the Outstation(s);
Update the local on-site copy of the register of seals applied;
Notify the MOA which Metering Equipment seal(s) has been broken and remade, within 2WD following the manual on-site interrogation of the Outstation(s). Details to include are:
- MSID
- Circuit name;
- Metering Equipment sealed;
- Date seals applied;
- Sealing pliers number; and
- The name of the CDCA operative who applied the seal(s); and
Keep a record of such notification for audit purposes.
The CDCA may only break and remake seals necessary in order to gain access to the local communication port.

1.7 Operational Emergencies

Seals may be broken by others under instruction from operational staff in an operational emergency or for safety reasons in an emergency, providing the MOA is informed at the earliest opportunity, stating the reasons for so doing. The MOA can then arrange to reinstate any seals affected. This includes equipment which is declared a “point of isolation” e.g. secondary fuses associated with metering VTs.

1.8 Routine Work and Metering Faults

All routine work and Metering System faults should be dealt with under Section 3.1 of this procedure.

Routine work shall be regarded as any work planned in advance which:

Is not associated with the CVA Metering Equipment but requires secondary metering VT isolation. This type of work is usually circuit planned outages.
Associated with the CVA Metering Equipment which is not due to a fault. This type of work is usually replacement of Outstation battery, calibration of Meters, accuracy tests of Meters.

1.9 Register of Sealing Pliers

For the purpose of maintaining an audit trail of the Metering Equipment seals applied, CVA MOAs and the CDCA shall maintain a register of sealing pliers detailing when, to whom and which unique pair(s) of sealing pliers have been issued for use. The register should additionally specify details of any lost or stolen pliers, any pliers sent for repair (CVA MOAs and the CDCA shall ensure that records relating to repairs are kept for at least 10 years) and the dates on which any pliers were destroyed.

CVA MOAs and the CDCA shall ensure their register of sealing pliers is made available for inspection by the BSC Auditor and the TAA for audit purposes.

1.10 Register of Seals Applied

CVA MOAs shall maintain a register containing details of when seals were applied to Metering Equipment for individual circuits. The details shall include:

Circuit name;
Metering Equipment sealed;
Date seals applied;
Sealing pliers number; and
Signature of person applying seals.

A template for the register of seals applied is provided in Appendix 4.3 of this BSCP, which may be used by CVA MOAs.

Copies of this register shall be kept on-site to enable the CDCA to carry out the visual inspection of Metering Equipment checks required in section 4.3 of BSCP05 ‘Meter Advance Reconciliation for Central Volume Allocation’ when it carries out Meter Advance Reconciliations (MARs) in accordance with BSCP05.

The CDCA shall update the on-site register of seals applied if it breaks and remakes a seal(s) to carry out an on-site interrogation of the Outstation(s). Upon receiving notification from the CDCA that a Metering Equipment seal(s) has been broken and remade, following the on-site interrogation of the Outstation(s), the CVA MOA shall update its local copy of the register of seals applied form.

In addition, this register of seals applied shall be made available for inspection by the BSC Auditor (off site) and the TAA (on site) for audit purposes.

1.11 Central Register of CVA MOA and the CDCA Sealing IDs

BSCCo shall maintain a central register of CVA MOA and the CDCA sealing IDs and issue a unique ID to each Qualified CVA MOA and the CDCA on request. The CVA MOA sealing ID will be associated with the CVA MOA’s Party Agent ID registered in Central Systems. The CVA MOA sealing ID may only be used by the CVA MOA it was allocated to and therefore cannot be transferred to any existing or new CVA MOAs. Where a CVA MOA ceases to operate in the CVA market, it will be required to destroy the sealing pliers associated with its CVA MOA sealing ID.

A CVA MOA can use an SVA MOA sealing ID in the CVA market where the CVA and SVA MOAs are from the same company. However, where the SVA MOA has more than one sealing ID, only one must be declared by the CVA MOA in order that the BSCCo can ensure that MOA sealing IDs remain unique in the CVA market.

Where the same MOA sealing ID is used in both markets, and the MOA subsequently ceases to operate in the CVA market only, the sealing pliers associated with CVA MOA sealing ID need not be destroyed as the TAA will have an effective from and effective to date for the relevant CVA Party Agent ID and therefore the MOA sealing ID. However, where an MOA subsequently ceases to operate in both SVA and CVA markets, the sealing pliers associated with the CVA MOA sealing ID must be destroyed in line with the SVA requirements.

Where the company performing the role of the CDCA ceases to perform that role it will be required to destroy the sealing pliers associated with its CDCA sealing ID.

The BSCCo will ensure that the up-to-date register of all CVA MOA and the CDCA sealing IDs, along with their effective from and effective to dates, are made available to the BSC Auditor and the TAA for audit purposes.

Key: S - Security seal I -Indicative seal P – Padlock

4.7.2 Types of Seal and Purpose

Table 1 identifies three generic types of ‘seal’ by purpose:

A security seal shall be used where both protection to avoid danger (to make opening of the equipment difficult) and indication of any interference are required. Where applied to Metering Equipment by a CVA MOA it shall be a specified seal as defined under ‘Specified Seal, Wire Rope and Associated Sealing Equipment’ below;

An indicative seal or label shall be used where only an indicative warning is required that work on the equipment could compromise the operation of Metering Equipment; and
A padlock shall be used to protect and to avoid danger on certain types of distribution/transmission equipment (to make opening of the equipment very difficult except to authorised persons having keys for the purposes of carrying out operations under required Safety Rules).

Specified Seal, Wire Rope and Associated Sealing Equipment

A specified seal is a particular form of security seal. The requirements of a specified seal are that it shall:

be a tin-plated, annealed, copper ferrule;
not be less than 5.0mm nor more than 7.0mm long;
have an internal diameter which is not less than 1.98mm nor more than 2.28mm;
be of some constant cross-section of such a size and shape so that its external perimeter lies within a circle whose diameter is not less than 4.06mm nor more than 4.6mm and the wall is nowhere less than 0.72mm thick; and
be crimped and marked on one side with the identification symbol appropriate to the MOA and on the other side with the 3-digit identification number of the Meter Operative. Alternatively, the specified seal can be crimped with up to 3 digits on each side to identify the Meter Operative and the identification symbol appropriate to the MOA, or the MOA's company name, may be impressed on a seal's flange or protuberance, provided that the design of the flange or protuberance is one approved by the BSCCo, from time to time.

The Requirements of Wire Rope are that it shall:

be manufactured from 7 strands of drawn, class Z, zinc-coated wire complying with BS 2763:1982;
have a diameter of not less than 0.914mm; and
have a breaking load of not less than 880N.

The requirements for sealing equipment are that it shall crimp specified seals onto wire rope sufficiently to withstand a tensile load of not less than 200N, in order to secure equipment so as to prevent accidental breaking or removal of the seal or wire rope.

Indicative Seal

The type used may be at the discretion of the party concerned. The main purpose, particularly on CT/VT equipment, is to warn persons intending to work on such equipment that their actions might interfere with metering integrity.

Padlock

General practice is to use brass bodied, hardened steel hasp locks with a common key suite so that any person with appropriate authority, issued with a master key, can open them. In some cases a coloured sheath (e.g. red) may be applied to indicate danger.

4.7.3 Guidance on Sealing Practice

General

Metering Equipment and related distribution/transmission equipment shall be sealed following initial energisation and shall be resealed following any subsequent works that require the removal of seals. The party carrying out such works shall be responsible for resealing equipment and for taking the removed seals from the site and destroying them, whether they are owned by that party or are the property of another party.

General Guidance Specific to Meter Operator Agents

Each Meter Operator Agent shall have a system for sealing and resealing, which shall include using a seal uniquely identifiable to it as specified in ‘Specified Seal, Wire Rope and Associated Sealing Equipment’ above.

4.7.4 Control of Specified Seals and Associated Dies

Sealing Pliers and Dies

Sealing pliers, to be used with uniquely identified dies for crimping and marking specified seals, must be provided by MOAs for each Meter Operative. Dies shall not be transferred between MOAs. In addition:

No MOA shall retain any duplicate sets of dies.
Sealing pliers, dies or specified seals shall not be used other than for sealing Metering Equipment.
Sealing pliers with dies that do not make legible marks shall not be used.

Destruction of Dies

A MOA shall be required to destroy sets of dies that have been damaged or are no longer required because the relevant Meter Operative will no longer be sealing Metering Equipment on its behalf.

In the event of a MOA ceasing to operate all sets of sealing pliers and dies shall be destroyed by it forthwith.
