Inspection and Maintenance
We offer independent advice regarding the condition of assets. Mondo has no affiliations with transformer manufactures or oil treatment/refurbishment operators.
To further ensure accurate results, we offer your team with training on sampling techniques and we can provide special sampling kits for sample collection.
Our NATA accredited laboratory offers a comprehensive range of oil and gas chemical analysis services.
- Dissolved Gas Analysis (Headspace DGA)
- Oil quality and condition
- Oil electrical insulating properties
- Monitoring of Oil’s additives
- Detection of cellulosic insulation condition
- Gas analysis including SF6 Gas Analysis (new and in use)
Mondo has a NATA accredited Electrical Test facility which conducts a vast range of repairs, tests and calibration on HV equipment.

A power transformer is a critical high value piece of equipment requiring thorough inspection and testing during manufacturing, installation, and commissioning stages.
Electrical testing can reveal manufacturing and design defects, internal deficiencies, damage or risk from transportation and onsite assembly.
Factory testing and on-site acceptance establishes baseline data for future testing and asset life management.
We offer a complete range of High Voltage diagnostic, pre-commissioning and condition monitoring testing of electrical plant up to 500kV.
The majority of electrical failures of electrical plant can be traced to insulation failure or breakdown. Only by establishing baseline data and performing regular periodic tests can trending data be post analysed to determine true indications of the insulation and plant condition.
Condition monitoring assessment of inservice transformers generally comprise of tests designed to identify degradation of dielectric paths due to thermal overload, ageing, moisture and mechanical wear and
vibration. The type of asset, age, condition, location, utilisation, loading and adopted asset management strategy, typically determines the frequency of periodic testing.
Electrical assets that are failing have a range of different characteristics that can be captured using a variety of hand-held and vehicle mounted sensors.
Our non-invasive testing services include
- Thermographic survey (infrared)
- PD airborne acoustic
- Ultrasonic scanning
- SF6 leak detection
- Cathodic protection design, installation and commissioning
- Stray current mitigation
- Electrical surge protection
- Pipeline potential surveys
- Tank potential surveys
- Coating defect surveys installation
- Installation and maintenance
- Testing of earthing beds
- Cathodic protection fault finding
- HV Tower footings corrosion protection inspections
Corrosion protection for high-value underground assets.
We design, commission, install and maintain cathodic protection systems for steel assets.
We conduct surveys to support the smooth operation of these cathodic protection systems, like coating defect surveys, corrosion potential surveys, electrolysis area tests and continuity fault surveys.
Our staff are fully qualified corrosion protection experts in a wide range of corrosion fields.
