Maintenance
Along with a range of services, HV Solutions offers maintenance on your own high voltage network. Maintenance is a legal requirement laid out in the Electricity at Work Act 1989, so not only is it good practice to have an annual inspection, it is required by law.
Our engineers carry out maintenance to meet BS 6626: 1010, Maintenance of Electrical Switchgear and Control Gear for any voltages that are above 1kV and up to 132 kV.
To achieve this, an authorised person will attend your facility and undertake the required operational checks to ensure that all electrical equipment is in a safe condition
Our senior authorised person will carry out inspections and testing of substations along with maintaining SF6 switchgear and CE2 Switchgear and transformers.
Following maintenance inspection and testing our engineers supply the results and reports for HSE.
HV Solutions offer rolling contracts for 1 and 4 years. We provide services and ongoing support 24/7/365.
As part of our maintenance services, we offer the following:
⦁ Conduct a survey for a report;
⦁ Change oil and filtration;
⦁ Check for any corrosion to transformers and repair and paint where needed;
⦁ Check problems with cables and glands;
⦁ Check oil circuit breakers;
⦁ Check and install batteries (per set);
⦁ Check vac circuit breakers;
⦁ Checking of bus coupling systems;
⦁ Checking partial discharge and pressure;
⦁ Ensure air transformers are clean and tight;
⦁ Fit new gages and taps where required;
⦁ Provide maintenance of substation services;
⦁ Provide reports;
⦁ Replacement of silica gel oil;
⦁ Sampling of oil;
⦁ Service ring main units (oil);
⦁ Servicing of ring main unit (SF6) gas check;
⦁ We check DNO isolation.
Low Voltage Equipment
In regards to low voltage equipment, we undertake maintenance on the following:
⦁ LV acb’s;
⦁ LV main switches;
⦁ LV panels.
Transformer / Switch Gear Oil
As part of our maintenance and services, we remove old oil if our inspections and testing have revealed acidy, dielectric strength or moisture.
Our annual inspection and operational checks include transformer oil sampling. Trend analysis is a key indicator towards helping to identify any potential transformer problems and can help in preventing catastrophic failure.
We have one of the largest stocks of associated HV and LV switchgear. This allows us to provide assistance quickly in the event of a breakdown, ensuring your site can be up and running again within a minimum time frame, keeping lost production down to the minimum.
Removal of the old oil is essential and should be undertaken as soon as possible otherwise you risk power failure to the site as high voltage equipment relies heavily on it to cool down the electrical current.
Our oil services include:
⦁ Conducting inspections and testing of oil;
⦁ Dealing with oil that has been contaminated;
⦁ Oil drains;
⦁ Providing oil testing report and results;
⦁ Topping up oil;
⦁ Transportation of oil;
⦁ Undertaking oil changes.
Power Factor Correction
Power factor correction is electrical equipment installed on your site and it is an essential piece of equipment.
We offer a repair and maintenance service for any existing equipment along with the installation of new equipment or extending any existing equipment.
Power factor plays a crucial role on site. When electrical equipment on-site uses power, it is called real power. However, power may be drawn on-site that is not used directly and this is called reactive power. The power factor is calculated based on the real and reactive power and if the site has a poor power factor; it means it is paying out for energy that is not used.
Power factor correctness, aka PFC, is equipment with technology helping to ensure a reduction in electricity bills as it can maintain the level of consumption of reactive power, keeping down losses. Having good power factor correction reduces the strain on electrical infrastructure.
HV Solutions can help to boost your power factor as we address the underlying causes of reactive loads, thereby reducing the demand for reductive power.
There are many negative impacts of a poor power factor. These include losses at transformers due to more power draining from the network and effective capacity reduction.
The benefits of improvement in power factor correction include:
⦁ A reduction of demand for power from the network resulting in lower bills;
⦁ Boosting the effective capacity of the electrical network;
⦁ Prolonging equipment lifespan;
⦁ Reducing the losses in supply transformers.
Old Equipment Demolition & Removal
We provide the demolition and electrical removal of old equipment from your substation site.
Here are just a few of the many reasons why you might require demolition and removal of equipment:
⦁ There may be health or safety issues and you need equipment removing;
⦁ You could be expanding your site or downsizing;
⦁ You might be upgrading and need to demolish and clear away old electrical equipment;
⦁ You might want equipment relocating to another area.
Whatever the reason for the demolition and removal of your electrical equipment, we undertake the job in a manner that is safe and cost-effective.
Our experienced team will remove your equipment whether it is:
⦁ CE2’s;
⦁ Generators;
⦁ Old or unwanted power factor correction units;
⦁ Old transformers;
⦁ Ring main units;
⦁ Switchgear.
Equipment painting / Repainting
It is essential to stop corrosion on existing electrical transformers, switchgear and ring main units. Over time exposure to inclement weather can cause disrepair and issues with equipment. If the equipment is in otherwise good working order and passing MOTs, you can further extend its life by painting/repainting.
In this service, our experts will give your equipment a coat of primer and oxide then follow this up with coats of protective paint. Our service costs a great deal less than having to replace your transformer, or another piece of equipment, due to corrosion.
Repositioning of Equipment
There may be times when you need repositioning of equipment. Perhaps this is to make way for additional equipment due to expansion? You might require your substation to be repositioned across to the other side of the site or even just a couple of metres. Making changes to the equipment at your substation is not an easy task and requires professionals. We offer a repositioning service.
This service is tailored to your individual requirements. It might be a single piece of equipment or machinery such as a transformer, cable, breaker or switchgear. On the other hand, you might require the reposition of your entire substation. Whatever the case we work with you every step of the way, from the initial planning of your move to the actual removal and repositioning of equipment or substation.
Energy Monitoring
HV Solutions can act in the role of the senior authorized person to undertake energy monitoring of your site.
Our expert team will provide consultant advice along with a full report to help you better understand your power balance on site.
You might be wondering why you require energy monitoring on your site? Well, here are just a few of the main reasons:
⦁ The power balance within the site may have been changed for one reason or another;
⦁ You may have built a brand new area on the site;
⦁ You might have had machinery on-site reconfigured;
⦁ You might want to balance the power more efficiently to save energy;
As part of our energy monitoring service, our expert team will come to your site and install portable energy recorders to the IV panels. These will be left to record results and then analysis of those results takes place before formatting them into graphs and readings. Following this, we use our software to produce a report for you, which you can then view.
