In 2017, as Switchgear specialists, Twyver executed a Smart Panel project with a new client. Having presented the Smart Panel at the Smart Factory Expo (NEC, Birmingham) last November 2016 for the first time, this is the first order of the Twyver Smart Panel allowing remote control/notifications via a Smartphone.
The project will entail the supply of a generator and the addition of an auto-changeover section to an existing Switchboard, the changeover section will be complete with outgoing supplies and automatic control.
One of the client major criteria is the special requirement of automatic text message response to allow the client to monitor the status of the generator (e.g. when the Generator is called to start and when the system returns to mains and the Generator stops). Being aware of the status of the board at all times will allow the client to monitor fuel use and maintenance requirements on the generator.
Containerised Switchrooms are designed taking into account customers detailed requirements.
Recent Twyver Switchgear Containerised Switchrooms have included High Voltage Switchgear, cast resin power transformers, LV. Distribution switchboards, power factor correction equipment, battery charging / switchgear tripping units, instrumentation / power monitoring devices, air conditioning, emergency lighting equipment together with general power and lighting.
The Containerised Switchroom Solution is often quicker and more cost effective than traditional brick built options.
A containerised switchroom can be readily installed either at ground or roof level.
Twyver Switchgear have designed, built, installed, tested and commissioned Packaged Sub-Stations for a many customers within the industrial and retail sectors and have a reputation for:

Recent projects for weatherproof equipment have included:
Motor Control Centres
Roof mounted Cast Resin Transformer
Our team of experts are on standby for our contract customers every day of the year, and are able to respond to critical onsite emergencies within guaranteed timescales of as little as 4 hours.
Being part of VINCI Energies, we are able to leverage our significant in-house manufacturing capability and supply chain to quickly solve and rectify problems.
Our aim is minimise any power downtime to your business and reduce the future risk by the use of onsite crash kits, critical spares.
As electrical connections become loose, the change in resistance causes increased temperature which can lead to component failure and unplanned outages / injuries. If left unchecked, heat can rise to a point that connections may melt and break the circuit; as a result, fires may occur. Thermography can quickly locate hot spots, determine the severity of the problem and help to establish the time frame in which the equipment should be repaired. If not rectified this could lead to a single point of failure and subsequent loss of supply.
With the increasing demands on building service supplies, the need for security of these supplies is absolutely critical.
Loss of supply can have the following consequences:
– Loss of life
– Major financial loss
– Loss of critical data
Regular, planned thermographic surveys by Twyver provide clients with fully detailed visual, written and electronic reports on the condition and performance of their equipment, together with appropriate recommendations and advice.
In many industries, mechanical systems serve as the backbone of operations. Typically when mechanical components become worn and less efficient, the heat emitted will increase. Consequently the temperature of faulty components or systems will increase rapidly before failure. Typical mechanical systems monitored in a predictive maintenance infrared programme include bearings, motors, pumps, compressors and conveyors.
Regular monitoring and verification checks will identify signs of degradation, which could result in future faults.
A typical Non-invasive Service visit follows our strict Safe Working Procedures and may include the following:
- Full visual inspection (where safely accessible)
- Thermographic survey
- Check function of meters and record values
- Check function and status of electronic surge protection
- Check operation of lamps and indicators
- Check operation of fans and thermostats
- Verify control circuit fuse continuity
- Record LV transformer values where applicable
- Clean of safely accessible surfaces / compartments
- AHF / STS servicing where applicable (in bypass)
Fully Isolated Service
A planned Fully Isolated Service should be completed every 3 to 5 years. We are expert in planning and delivering an Isolated Service to minimise the impact on your business. These are usually completed out of hours.
A typical Fully Isolated Service may include the following:
- Prior to shutdown, live visual inspection of lamps and meters with readings noted
- Verify torque tightness of all power connections
- Check tightness and mechanical operation of all switching devices
- Check tightness and condition of pan assembly connections
- Check tightness and condition of outgoing terminals
- Check operation of lamps, indicators, fans, thermostats, control circuit fuse continuity
- Check operation of doors and interlocks
- Clean of panels inside and out where safely accessible, removal of debris / particulates / residue and photograph for inclusion within the report
- Full torque testing and cleaning of HV transformer and enclosure
- Insulation and continuity testing of LV transformer
- ACB / MCCB tested and serviced
- Active Harmonic Filter (AHF) servicing
