HVMS
Specialist Services
HVMS was founded in 1988 to provide a complete, cost
effective service to users of high voltage distribution systems up to
132kV.
Since that time the services have expanded from straight forward HV/LV
maintenance to complete turnkey power distribution packages.
Other services include protection studies, system design, installation
and commissioning of capital equipment plus HV/LV cabling services and
associated civil works such as excavation, trenching and re-instatement.
Many clients use us as independent consultants and specialist system
protection engineers for network co-ordination. Being a privately owned
independent company, we are often required to compile inspection surveys
and fault reports. Fault Level & Discrimination
Studies
When switches or relays malfunction under fault
conditions the consequences can be severe, ranging from damage to
equipment and probable plant shut down, to safety risks for personnel.
Detailed design and application of adequately rated fit for purpose
equipment is paramount in any electrical distribution network. HVMS have
completed numerous study reports, mostly prior to, but some during large
construction and installation programmes.
The study incorporates three main sections, the first a data base
representative of the distribution system, secondly formatted schedules
of protection settings and blocking functionality of relays, and thirdly
a conclusion highlighting areas of concern with recommendations.
Finally, HVMS can work with the M&E contractor on the final integrated
commissioning plan, relay setting/programming, switching logs, final
commissioning and co-ordination of the complete electrical scheme, using
our Senior Authorised Persons. Thermographic
Inspections
Thermographic inspections should be a regular part of
a predictive maintenance programme. An indication of impending faults in
mechanical and electrical systems and components is an increased
temperature due to increased resistance and friction.
This temperature increase can be detected and quantified using the
latest thermal cameras. HVMS’s state of the art thermal infrared cameras
operate in a similar way to a standard video camera and an image of the
temperature distribution of the component can be obtained. Should any
part of the component be significantly warmer than other similar parts,
a recording of the suspect component is taken. The magnitude of
temperature rise will be illustrated and the seriousness of the fault
can be determined. Routine Maintenance & Inspection
Routine maintenance of high & low voltage plant
should be carried out not simply to ensure reliable and economical
service, but to comply with the provisions of the Health and Safety
Executive.
In addition, all maintenance and inspection is carried out as
recommended by the equipment manufacturers and as required by BS
6626:1985 Code of Practice for Maintenance of Electrical Switchgear and
Control Gear. Such works are implemented in compliance with the
Electricity at Work Regulation 1989.
Only trained, competent, Authorised and Senior Authorised personnel are
utilised by HVMS. Our Engineers and Technicians are fully conversant
with all varieties of electrical equipment, not to mention the differing
handling, storing and disposal requirements.
HVMS strictly follow schedules of work and report on the condition of
plant before and after remedial treatment with recommendations for
future consideration. A comprehensive written report is issued to the
client upon completion of work. Safe Working Systems
Even during the construction of an HV network there
is a legal requirement of customers under the provisions of the
Electricity at Work Regulation 1989 to have appointed trained and
competent staff.
HVMS can provide a ‘Safe System of Work’ for the operational control of
the HV Network, during and after the construction phase utilising HVMS
Distribution Safety Rules and principally the provision of suitably
trained and experienced ‘Senior Authorised Persons’.
Through these staff we are able to provide temporary operational control
of the network and manage the transition from construction phase though
to client handover.
