Ungrounded power systems and EDS
Ungrounded power systems are utilized in demanding industry sectors to reduce fire risk, increase resilience and improve electrical safety, ensuring a reliable and operational power system.
Typical examples of safety-critical installations with grounded power systems are oil and gas platforms, industrial plant, manufacturing, ships, substation switching and rail networks. There are severe consequences that come with downtime in these industries.
How does EDS reduce the loss of revenue?
EDS finds developing ground faults without disconnecting the electrical installation. With just an IMD, you still need to isolate circuits to determine where the earth fault is. This is time consuming and expensive. The cost of finding ground faults in critical locations is high due to man power, downtime required and accessibility.
Knowledge of the fault location allows isolation of power to only the faulted circuit for repair, allowing the remainder of the system to remain operational, reducing the cost of fault finding and rectification.
Knowing when and where ground faults are developing gives you time to react from an operational perspective so you can plan your downtime, purchase new equipment to replace ageing assets, or schedule maintenance before a failure occurs.
Weak points in the electrical infrastructure can be identified, trends monitored, and when required, action can be taken where necessary.
Frequently asked questions
Can EDS be fit into an existing installation?
Yes, we even have split-core CTs, rectangular, circular and flexible CTs which generally makes retrofit neat and simple.
Should EDS be fit in every final circuit panel board?
It can be, but you could just utilize it on your most critical equipment.
Is EDS portable?
Yes, we also have a hand held, portable EDS fault location kit that is ideal for the final pinpointing of an earth fault without needing to disconnect.
Can I connect it to an existing BMS monitor, panel annunciator, etc.?
Yes, we can provide options for this with an understanding of your application.
