Load spikes increase temperature
Uncertain status of aged transformers at
Australian holiday destination
• Unknown ability to handle increased load due
to Commonwealth Games
• Urgent request from Operations team to load
aged transformer over nameplate
Reports enabled engineer to go online and
answer the question immediately
• Transformer still bearing summer load today

OpEx: Improved visibility for volatile loads
Increased risk
due to load
volatility
Uncertain status of aged transformers
• Increased risk from volatile loads
Changes to long-term load profile from
• Solar farm connections
• Impact of high-density rooftop solar
• EV Charging
Alternative options
• Full DGA/monitoring suite
• Immediate replacement
Pricing showed clear ROI and enabled asset
managers to assess the impact of the new load
profile on insulation life left.

Uncertain status of aged transformers
• Unknown ability to handle increased load,
particularly over summer
Transformer earmarked for replacement based
on nameplate age
• Forecast transformer and substation upgrade to
current standards ~$5M CapEx
Reports over summer 2017 showed better health
than expected.
Replacement delayed by 10 years
$2.7M NPV saving
ROI > 100 x

• Extensive refurbishment of transformer tap
changers and bushings
• EcoStruxure Transformer Expert installed
after maintenance showed investment was
wasted due to poor state of insulation
Clear business case for monitoring before
significant maintenance expenditure

Water ingress analysis
Water content paper analysis over one year
• Significantly greater than that expected
due to depolymerisation
• Increase explained by moisture ingress
into leaking transformer
• Moisture ingress is irreversible
Maintenance needed to prevent further
irreversible asset degradation

OpEx: Impact of drying
Water activity over 18 months
• In a humid climate, transformers are
regularly dried
• Is this practice having long term
positive impact?
Water activity crept up after the
completion of drying in July 2019 and
2020 as expected, but clearly showed
positive long-term results.

OpEx: Impact of transformer dry-out

20. Internal
Heat wave and cold change cycles over summer
• High air-conditioning use, followed by abrupt
drop in load
Temperature and moisture is dynamic
• Driven by WCP
Water dynamics are not symmetrical
• Water content of oil can become dangerously
high reducing dielectric strength
