Protection & controls
Taurus Protection & Controls brings testing, commissioning, maintenance, and engineering support under one structure to help verify that critical protection systems operate as intended.
START VERIFYING SYSTEMS.
STOP TESTING COMPONENTS.
ONE SYSTEM. ONE TEAM. FULL CONFIDENCE.
The Problem
Protection systems change over time.
Relay settings are updated. Equipment is replaced. Wiring and communications are modified. New loads and system configurations are introduced.
When those changes are not fully verified across the entire protection scheme, gaps can develop between individual devices and how the system actually performs.

What This Creates
When protection systems are not fully verified, the result can be:
Unexpected trips
Misoperations
Incorrect or outdated settings
Commissioning issues
Coordination gaps
Uncertainty before energization
Increased reliability risk
THE RELAY MAY BE WORKING. THE SYSTEM MAY NOT BE.
SMALL GAPS CAN CREATE BIG CONSEQUENCES.
The Taurus Approach
We look beyond the individual device to evaluate the complete protection scheme.
Step 1: Understand the system
Review protection schemes, relay settings, drawings, system configuration, and operating requirements.
Step 2: Verify the Components
Test relays, CTs, PTs, trip circuits, breakers, communications, logic, and associated equipment.
Step 3: Test the Scheme
Confirm that individual components work together through functional, end-to-end, and commissioning testing.
Step 4: Stay engaged
Support preventive maintenance, outages, troubleshooting, system changes, upgrades, energization, and emergency response.
Where We Start
Protection & Control Testing
Protective relay testing and commissioning, relay calibration and functional testing, secondary current and voltage injection, CT/PT testing and verification, relay settings verification, protection logic and scheme testing, and end-to-end protection testing.
Commissioning & Energization
Protection system commissioning, trip circuit and breaker control testing, SCADA point-to-point testing, RTU testing and commissioning, communications and protocol testing, interlock and control scheme testing, energization, and startup support.
Maintenance & Troubleshooting
Preventive maintenance, troubleshooting, emergency response, outage support, maintenance testing, breaker troubleshooting, and ongoing support after system modifications or unexplained protection issues.
What This Changes
Better visibility across the protection system
Fewer gaps between individual devices and the complete scheme
Fewer vendors and handoffs
More confidence before energization
Stronger support for ongoing maintenance and system changes
VERIFY MORE. ASSUME LESS.
More coordinated testing and commissioning
Better insight after unexplained trips

How Often Should Protective Relays Be Tested?
There is no single testing interval that is right for every protection system. Testing frequency should consider relay technology, equipment criticality, operating environment, system history, manufacturer recommendations, applicable standards, previous test results, and the asset owner's maintenance requirements.
-
What Causes Protective Relay Misoperations?
Protective relay misoperations can be caused by incorrect or outdated settings, equipment failures, wiring and installation errors, logic and configuration problems, communication failures, and incomplete commissioning.
