Data center substation energization software for campuses where one interconnection point serves every hall on site.

The campus substation, HV switchgear and step-down transformers are commissioned by a specialist HV contractor working to a different standard and timeline than the hall-by-hall build, but every hall depends on it.

Protection relay settings, coordination studies and utility interconnection requirements are often finalised late, which puts pressure on the energisation date without pressure on the evidence behind it.

Deskely treats the substation and HV distribution as their own subsystem with hard prerequisites, so HV energisation cannot be approved ahead of protection testing and utility sign-off simply because the schedule needs it to happen.

HV technicians record insulation resistance, transformer oil testing, relay injection testing, CT/VT ratio verification and protection coordination confirmation on tablets, with mandatory measured values at every step.

Utility company witness tests and approvals are logged against the interconnection asset, keeping the external sign-off in the same register as the internal commissioning evidence.

Punch from a protection setting error or a failed insulation test is categorised as blocking HV energisation, which is treated as a distinct and higher-consequence gate than hall-level punch.

Every transformer, switchgear lineup and distribution panel added as the campus grows changes available fault current somewhere upstream or downstream of it, which changes the arc flash incident energy calculation for panels that weren't part of the new scope at all — a fact that's easy to miss when the arc flash study is treated as a one-time deliverable rather than a living document tied to the electrical system's actual configuration.

Utility interconnection agreements typically specify grid code compliance requirements — protection coordination with the utility's own relays, fault ride-through behaviour, disconnection time — that have to be demonstrated to the utility's satisfaction independently of the campus's internal commissioning sign-off, and those two approval chains rarely share a record set.

Deskely ties the current arc flash study revision and PPE category to every HV and distribution asset it covers, so a configuration change that invalidates an existing label is a visible discrepancy, and holds the utility's own witness and approval records against the interconnection asset so both approval chains close from the same evidence.
