Risk management

Seeing the unseen electrical and mechanical issues

Risk and Electrical Switchboards and Infrastructure

The key objectives in risk fall into two categories

• Staff welfare and safety – identifying issues in electrical switchboards

• Continuous supply of power – ensuring equipment does not fail creating risks.

No Issues as I am aware

Consequences of electrical switchboards faults and issues • Fire – Electricity major factor in fire cause. • Safety – incidents with electrical injury is often higher

than perceived. • Service delivery interruption. • Energy Costs – if power factor units and other vital

components not performing correctly. • Major Issue – Publicity - Impact on, share

holders/members.

Thermography General Requirements

• What is a Thermographic survey?

• Using infrared images to measure temperature differential and graphically illustrate issues such as electrical anomalies, overheating, metal wear, insulation degradation, identifying leaks , observing air conditioning blockages are a few of the applications.

19

The issues below if addressed will ensure that your survey if required for legal, warranty or insurance claim purposes is not compromised. •Specialised equipment regularly serviced and calibrated. •Trained consultants with thermography qualifications and significant experience in electrical, mechanical and building industries •Operating to appropriate standards and guidelines. Australia / International . •Conduct surveys with due diligence to safety and addressing risk issues. •Reporting completed to a high standard that shows asset condition insights and issues to be addressed. •The thermography service company can show evidence of continued research and peer review, with ongoing professional development.

Board, Director and Senior Management level. Risks that an effective thermographic survey can address for organisations.

• Ensure all assets are checked •Survey is independent •Monitor faults to check for ongoing issues. •High Voltage Low Voltage •Expectation of Insurance objectives or addressing issues that are to be investigated. •Critical and high risk assets. •Performance of Assets Power Factor Correction unit – not operating creating costs

These crimped connections between these transformers appear to be loose. They should be checked. A failure here would shut down the entire system.

MOTORS – maintenance and performance

24


This motor is running too hot. Most motors are rated at 40C (104°F) over ambient for a maximum heat rise. Once a motor reaches that maximum for any length of time, the life expectancy of the motor is cut in half. For every 10° above that maximum heat rise, the life expectancy is cut in half again. Heat could take a 20 year motor and turn it into a 5 year motor pretty fast. This motor is probably overloaded or over greased.

Thermography Key Points Training Competence Calibrated Equipment Suitability of the equipment Standards Anecdotes – misdiagnosis – equipment – reporting.

Thermographic Reporting Objectives •Approach asset surveys – Compliance or proactive. - How often to inspect. •Reporting – Your level of requirements •Maintenance – Overview of asset health What needs to be addressed with issues discovered? •Cumulative overview – Comparison online or hard copy showing past reports. •Management Overview – History of issues accessible, summary of compliance •Asset Management –Trending of individual asset performance under loading.

Overview of Reporting system. Routes of locations and equipment are bar coded for the automatic retrieval of each asset’s past inspection history. Reports – Options that can be generated by Thermoview • Historical Test Status Matrix for every survey completed. • Infrared Documentation pages – Issues to be addressed by priority. • Before vs. After repair function if required. • Problem Trending • Prioritized List of Problems • Cost Benefit Analysis – • Inventory Test Status • Problem Status/Aging and trends. • Visual Problems - • Equipment Baseline Trending Saving you time in analysis and asset review.

FLAT ROOF LEAK DETECTION

38


Interior infrared survey conducted during daytime hours reveals central area saturated with moisture and in need of immediate repair.

MOISTURE CONTAMINATION

39


The thermogram of this vinyl-sided 3-floor apartment house clearly shows the path of a serious leak from a washing machine on the third floor, which is completely hidden within the wall.

PARTIALLY BLOCKED DRAIN PIPES

40


Image shows pipes becoming blocked. Further build up has likelihood of a

serious blockage and consequent damage.

WATER LEAKS

41


Water logged cool room insulation.

STRUCTURAL STEEL

42


This is usually where the bars are joined in a bolted splice. Over time the expansion and contraction from heating and cooling along with vibration from the plants daily routines, will cause the bolts to become loose. There is no way to see this without Infrared Thermal Imaging. This was done from the floor, without climbing up and opening the boxes.

CONCRETE DETERIORATION

43


Note the de-bonded concrete layer on viaduct parapet wall. The thermographic image has made it possible to efficiently and accurately detect the precise development of loosening or cracking concrete that can lead to concrete exfoliation in future. The safeguarding of third parties against potential disasters is dramatically improved through thermal imaging.

• Refrigeration – Maintenance – Energy Studies In alliance with Cundall Sustainability Consultants • Air Leakage in cold stores, trucks, containers and refrigerated equipment. • Degradation of insulation in panels. • Poor door seal performance. • Electrical switchboard review. • Electric Motor heating. • Moisture build up. • Roof leakage • Thermal bridging. • Insurance – risk management validation. • Cost Benefit Analysis

PROCESSING

45


Here we used Infrared Thermal Imaging to see the level of liquid in the tank. The vapour space above the liquid is warmer than the liquid and thus we see the temperature differential. The liquid will have a higher thermal capacitance (ability to store energy) than the vapour space, and that is why we can see the difference.
