The opening of this new facility in Moranbah makes the occasion even more exciting and we look forward to working within this region and the local community to build a great business that is rewarding for everyone”, said Don.

Ampcontrol Named NSW Minerals Council 2018 Outstanding Supplier For H3RO

On 15 March, Ampcontrol were named as the 2018 NSW Minerals Council Outstanding Supplier at the annual Industry and Suppliers Awards Dinner at NSW Parliament in Sydney.

Ampcontrol’s General Manager of Sales, Garry Hillier accepted the Outstanding Supplier Award for the development and supply of H3RO, a fibre based communications and networking solution for underground mining and industrial applications, which has been adopted by 16 mining operations since its launch in 2015.

Rod Henderson, Ampcontrol CEO and Managing Director said “Our H3RO product has been an innovative game changer for Ampcontrol, enabling the effective use of fibre technology in underground mining operations that has historically been difficult to achieve.”

“We knew our customers wanted a reliable fibre optic solution for their underground operations, so we listened to their feedback and proactively addressed the challenges they were experiencing by providing a robust, cost effective, portable and easy to install fibre optic solution.”

“Being recognised as Outstanding Supplier of the Year is a true testament to everyone at Ampcontrol and it’s humbling to know that the H3RO product has been so well received in the market” added Mr Henderson.

The Universal Appeal of the H3RO solution

Ampcontrol’s H3RO product has also been on display this week at the Leading Age Services Australia 2018 Conference on the Gold Coast, welcoming 350 delegates through the conference exhibition stand.

As H3RO is a fibre optic communications solution, it is applicable to support the continued development of aged care infrastructure projects.

John Hooper, H3RO and Networking Automation Product Manager said “We’ve been demonstrating how H3RO can be used as part of passive optical network architecture to improve ICT reliability, while reducing the cost and complexity by converging the connected services for smart buildings.”

Touch Potentials – Typical Practice Is Not Necessarily Safe

Traditional earth fault limits, earth loop impedances and protection clearance time ‘rule of thumb’ do not always result in safe or compliant systems.

Find out more below or download as a PDF version.

A Typical Underground Example

Touch Potentials


A typical 1000V underground supply system commonly has a 5A earth fault limit. The cables feeding outlet control and the load are often protected by earth continuity relays with a 45Ω pilot earth loop impedance limit. Allowing for the pilot resistance of the installed cable length, could see the total return earth impedance for an earth fault in the load as high as 75Ω.

Worst case touch voltage is: 75/(115+75)*577 = 228V 

Total clearance time for outlet E/L:

  • Earth leakage relay 50 msec (instantaneous)
  • Interposing relay delay 20 msec
  • Breaker/contactor delay 130 msec

= a total clearance time of 200 msec



Not compliant or safeThe scenario is typical of underground practice as the key operating parameters are consistent with values allowed in standards

  • 5A earth fault limit
  • 45 Ohm earth return impedance limit

The potential touch voltage clearance times are to the right of the safe area of the wet area curve (Lp) in AS/NZS4871.


What you need to do

The 2012 changes to AS/NZS4871 are more significant than generally appreciated. Traditional parameter values available under standards are not necessarily ‘safe’ when configured into a practical system.

Removal of prescriptive limits on key parameters including earth fault limits, trip settings and clearance times, requires all design settings to be examined from first principles.

Regardless of whether they fall below the wet area curve or not, all protection parameters should be justifiable as being as low as reasonably practical.

How to get there

  • Complete an audit of your system against the requirements of AS/NZS4871
  • Carefully consider the fundamental parameters including:
    • Earth fault limitation
    • Return earth impedance limit
    • Tripping ratio and total clearance times
  • Review underground substations for compliance against AS/NZS4871 and Safety Bulletin SB11-04 (variable speed drives and fitment of wideband earth leakage)
