Core Services
Ten services, one standard of work.
Each one has its own page covering scope, equipment, standards, and deliverables.
Why NewEra
Results you can trust.
Focused protection & controls expertise, backed by four commitments.
Relay panel wiring
01
Fully Documented
Jobs close with a clear written record, plus verified relay performance where protection is in scope.
02
Beyond Protection Function Verification
Pickup and timing are just the start. Digital trip and interlock signals are proven with the same rigor as hardwired ones.
03
Safety Is Foundational
OSHA 10-trained technicians work to NFPA 70 and MSHA requirements, backed by continuous safety training.
04
Fast Field Response
From planned outages to urgent field validation, work is scheduled around your window, with quick turnaround on findings.
Protection & Controls
Protecting power systems, one relay at a time.
Protection proven by test, not assumed. Relay settings are applied and verified exactly as issued by the engineer of record or client.

Relay & Logic Programming
Issued protection logic and alarms programmed, then checked point by point before energization.
Secondary Injection Testing
Three-phase injection proves pickup and timing, plus differential slope and distance reach.
IEC 61850 & GOOSE Validation
GOOSE messaging integrity, protocol-level diagnostics, and communication architecture assessment for IEC 61850 substation networks.
Time Synchronization Validation
Time sources and relay clocks verified so event records align across the system — essential for accurate fault analysis.
Fault Event Analysis
Relay event records and oscillography reviewed to explain operations, isolate root cause, and confirm protection responded as set.
Asset Protection Verification
Transformer, generator, and motor protection schemes verified, down to overloads and stalling.
Capabilities
Acceptance and maintenance tests, matched to the equipment.
Each scope is set by the asset’s condition and its role in the system.

Standards & Methodology
Standards-driven testing. Every test. Every time.
How every job runs
01
Scope & Review
We review drawings, one-lines, and the settings issued by the engineer of record or client before mobilizing.
02
Safe Mobilization
Job briefing, hazard awareness, arc flash precautions, and proper PPE are in place before any test begins.
03
Test & Verify
Devices are tested individually, with readings evaluated against acceptance values.
04
System Validation
Trip circuits, control logic, and communications are validated together as one working system.
05
Document & Deliver
Detailed technical documentation records results, as-left settings, and deficiencies — ready for your records and the next test cycle.
