We can work on any system, add additional switches, modernise it and give you, the customer what you need when you need it.

Switchgear Manufacturer Specialist

We are one of the leading UK switchgear manufacturers with vast experience with connectors and switchgear. For high-voltage electrical equipment to operate safely and efficiently, the electrical supply from the switchgear unit needs to be optimised and tailored to your site requirements. This is where we provide the most suitable solution to ensure your electrical system is safe and reliable.

As well as manufacturing switchgear, we also offer the following when it comes to switchgear systems:

  • Full on-site switchgear installation
  • Thermographic surveys
  • Full site and distribution system surveys
  • Protection relay testing
  • Modules and plates
  • Maintenance and repairs to any power distribution panels
  • Power factor correction and voltage optimisation equipment
  • Testing of a transformer
  • Decommissioning of systems
  • Most of all, we can be there when you need us most

We build our switchboards in-house and can offer fast turn-around times to suit your requirements, and we have the capability to retrofit and repair older systems. Our switchgear systems contain the best components money can buy, ensuring the highest quality for our clients.

Improving Existing Switchgear

At Johnson & Phillips, we manufacture and install switchgear using the latest technology. However, we also provide many upgrades that will improve the efficiency and bring older switchgear systems up to date.

Below are some of the available upgrades:

  • Installation of thermal sensors for main switchboards, effective in diagnosing and rectifying faults.
  • Replace old circuit breakers with the latest system, which offers far greater capabilities.
  • Upgrade existing relays to improve the reliability and safety aspect of the switchgear.
  • Install partial discharge monitoring that ensures the equipment used is properly maintained.
  • Improving power monitoring equipment to provide modern displays compared with the older analog meters.

Refurbishing your existing switchgear is a cost-effective solution, and we offer a range of upgrades. However, deciding when to replace the switchgear systems can depend on a range of factors such as the condition, age, frequency of faults, performance history and more. We strongly recommend that you get in touch and have one of our engineers thoroughly test the system.

Frequently asked questions

Q&A About Our Switchgear Services

Switchgear consists of circuit breakers and electrical disconnect switches that distribute, protect, and isolate circuits and equipment. High-voltage switchgear also continually monitors the circuits and provides data on a control panel.

Switchgear controls, protects and isolates electrical circuits using devices such as circuit breakers and relays, managing the flow and safety of electrical systems.

This differs from transformers because a transformer transfers electrical energy between circuits, changing voltage levels for efficient power distribution. They also consist of primary and secondary windings and a magnetic core and are crucial for voltage transformation and power transmission.

Switchgear controls, protects, and isolates electrical circuits using devices such as circuit breakers and relays, managing the flow and safety of electrical systems.

This differs from switchboards because a switchboard distributes electricity to various circuits within a facility. It contains panels with switches, fuses, and circuit breakers that route power to different areas, enabling control and monitoring of electrical distribution within a building or industrial site.

In electrical switchgear rooms, the following should be stored:

  1. Switchgear Equipment: Circuit breakers, relays, fuses, and other control and protective devices.
  2. Documentation: Maintenance manuals, operation guides, and schematics for the equipment.
  3. Safety Gear: Insulated gloves, face shields, fire extinguishers, and other personal protective equipment (PPE).
  4. Tools: Insulated tools for maintenance and repair tasks.
  5. Spare Parts: Replacement fuses, circuit breakers, relays, and other essential components.

To ensure safety and accessibility, non-essential items such as flammable materials, unrelated equipment, and other materials should be avoided.
