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.
