High Voltage Commissioning

High Voltage Commissioning

Site commissioning services up to 132kV or ad-hoc management of a protection team are key services that CleanTech Controls can provide on site at utility substations or private substations.

High Voltage Commissioning refers to the process of testing and verifying the performance and safety of electrical equipment or systems that operate at high voltage levels before they are put into operation. High voltage typically refers to voltage levels above 1,000 volts (1 kilovolt or kV), and it is commonly encountered in various industries, including power generation, transmission, distribution, industrial facilities, and more.

The commissioning process is critical to ensure that high voltage systems operate reliably, efficiently, and safely.


High voltage commissioning is a critical step in ensuring the reliability and safety of high voltage electrical systems. It helps identify and address potential issues before a system is put into service, reducing the risk of costly downtime, equipment damage, or safety incidents.

Here are key aspects of high voltage commissioning:


The primary goal of high voltage commissioning is to ensure that electrical systems and equipment are installed correctly, function as intended, meet design specifications, and comply with safety standards and regulations.

Safety Precautions

Safety is of paramount importance during high voltage commissioning. Strict safety protocols and procedures must be followed to protect personnel and equipment from the dangers associated with high voltage electricity, such as electrical shock and arc flash hazards.

Distribution Panels

High voltage commissioning typically involves a series of tests and inspections on various components and systems, including:

Circuit breakers and switches
Cables and cable terminations
Surge arresters
Protective relays
Control and protection systems
Grounding systems

Functional testing

Functional tests are performed to ensure that electrical equipment operates correctly under different load conditions and in response to various control signals. For example, circuit breakers should be tested for proper opening and closing operations.

Insulation testing

Insulation resistance tests are conducted to check the integrity of electrical insulation in cables, windings, and other components. Insulation testing helps identify any weaknesses or defects that could lead to electrical faults.

Partial discharge testing

Partial discharge tests are used to detect and assess partial discharges within high voltage equipment. Partial discharges can be indicative of insulation breakdown or degradation.

Protection Relay Testing

Protective relays are essential for ensuring the safe operation of high voltage systems. Commissioning includes verifying the correct settings and functionality of protective relays.

Documentation and Reporting

Detailed records of all commissioning activities, test results, and any issues identified are maintained. These records are crucial for compliance, future maintenance, and troubleshooting.

Commissioning Team

High voltage commissioning is typically carried out by a team of experienced engineers and technicians with expertise in high voltage systems and equipment.

Commissioning Plan

A comprehensive commissioning plan outlines the specific procedures, tests, and schedules for the commissioning process. It helps ensure that all necessary steps are taken in an organized manner.

Regulatory Compliance

High voltage systems must comply with applicable industry standards and regulations. Commissioning activities are often subject to regulatory oversight.

What Our Clients Say

This company is excellent. We go to them first for Grid Protection Units. They offer great value especially when you add their top notch customer service. As usual, we needed something STAT this week and the team didn't leave us hanging, even finishing it up and testing on a Saturday to meet our timetable. Graham Dennis shout out.
Mark Horsfall (Simmark)

CTC has always provided great service on the many occasions we have worked with them on our solar projects. They are reliable, responsive, and overall an excellent company.
Daphne from The Greenguys Group

Big fan of these guys - always answer the phone. They helped me out when Endeavour Energy required a neutral voltage displacement protection function on the solar installation
