Online Partial Discharge Testing

---

Question:    What is the quickest way to shut down your production?

Answer:       Lose your high voltage side of your transformer, it's not just your low voltage side you 

                     need to watch.

Partial discharge is a factor in 85% of unexpected substation failures.  So, looking after your HV main supply is important to your productions.

Here is where Coombs Electrical Services can help you.  We will look after your HV by testing for partial discharge on your HV equipment  (including any HV power lines) when they are still live and running, resulting in no loss of production.

We test for partial discharge by means of Ultrasonic Testing and TEV (Transient Earth Voltage) Testing,  and provide a comprehensive report.

Another big advantage is reducing the risk for your staff and property by being pro-active.  If your company is using the ISO 55000 Asset Management System,  our reports work in well with this system because data such as this is critical for asset management.  Even if you think of going down that road our data will help you achieve your targets.

Coombs Electrical Services aim is to help find issues before they can knock your power out and give you a big headache.  Our aim is to give you more control of your network and lets you choose when to take pieces of equipment out.

By being proactive can save yourself money, time,  and other gains, such as:

• No time spent maintaining equipment that does not require it
• Making informed maintenance timing decisions
• Extending maintenance intervals
• Reducing the risk of catastrophic failure resulting in large downtime
• Less production time lost for smaller issues.
• Less money lost on call out wages
• Less time rearranging the work that was not done when your crews were responding to break down
• Less parts costs if you repair an issue before it damages more of the equipment (Not many companies have a spare transformer sitting in the yard)
• Helping determine optimum replacing strategy
• Reducing capital expenditure
• Supporting investment decisions and timing
• Improving asset performance and keeping maximum asset availability
• Lets clients focus on their primary function

Areas we can test for you:

• Transformers
• RMU
• HV Switch room
• Switch Yards
• Overhead power lines
• Overhead equipment
• Most HV equipment

So... a little cost now can save big money later and give you more control back.
