INDUSTRIAL & MARINE ELECTRICAL SERVICES

No matter what service you need, we guarantee:

• Emergency response 24 hours, 7 days a week
• Quick turnaround times — even for services demanding large amounts of engineering
• Specialization on large electrical apparatus maintenance and troubleshooting
• Electrical maintenance and acceptance testing services according to customer specifications or current ANSI/NETA MTS, Standard for Maintenance Testing Specifications for Electrical Power Equipment and Systems
• Technicians with customized safety and technical training to meet mandatory requirements and applicable laws

• Providing complete design of substation and generator systems
• Meeting the operational needs of the customer
• Coordinating electrical systems to meet reliability requirements and standards
• Completing upgrades and modifications

• Dispatching crews to affected locations across the United States and around the world
• Assessing electrical damage
• Inspecting equipment and quality control
• Repairing, if salvageable, or replacing equipment
• Providing installation and commissioning
• Restoring facility to service

• TDE has helped customers with:
• Installing new substation and switchgear
• Upgrading relays and protection equipment
• Retrofitting old or obsolete equipment
• Adding emergency equipment (generators)

TDE is involved with:

• Designing and specification of equipment
• Providing and reviewing red-line drawings and one-line diagrams
• Installing equipment
• Testing and commissioning new systems

• Responding to unplanned outages
• Providing 24/7 response to get equipment back online
• Troubleshooting and repair
• Conducting root cause analysis of electrical incidents

• Short Circuit, Coordination, Arc Flash, Motor Starting, and System Stability Studies: Performed by senior electrical engineers with many years’ experience, which provides the best value.
• Commissioning: Electrical systems, switchgear, apparatus, etc.
• Complex Microprocessor Relays: Replace old obsolete mechanical relays with new type electronic relays, rewiring into the circuitry by working with the customers’ engineering staff. Then test the current transformer, relay, and circuit breaker to ensure the protection system is operational.
• Oil Transformers: Oil sampling and trending, replace faulty bushings or leaking bushings, perform diagnostic services such as Doble power factor testing, sweep frequency response analysis (SFRA), and partial discharge analysis.
• High-Voltage Switch Gear: High-voltage circuit breakers, high-voltage dielectric testing, Doble power factor testing, partial discharge analysis, circuit breaker time travel analysis, and circuit breaker vacuum bottle testing using magnetron atmospheric condition (MAC) testing.
• High-Voltage Cable: Terminations and splicing with nationally certified (NCSCB) technicians. Also, testing using AC 60 Hz dielectric, VLF, VLF-Tan Delta testing of high-voltage cables or partial discharge.

TDE provides a wide range of power monitoring services. We use a variety of measurement tools and methods and apply several standards. TDE evaluates and monitors the accuracy, resolution, bandwidth, transducers, interference and communications needed to meet customer requirements.

Our services also include:

• Recording for extended periods of time to perform power quality analysis of electrical power systems
• Finding the cause of many power system disturbances, such as harmonics, transients, and voltage sags and swells
• Using power monitoring to plan for future additions to the electrical system together with computer system studies

• Power Monitoring: This includes simple monitoring for load studies and advanced power conditioning monitoring for detecting defective power availability. Customers that require detailed analysis of voltage irregularities (unbalanced voltage, voltage spikes, fluctuation voltages, etc.) and amperage problems (current transients, current imbalance, current sag, etc.) will need advanced power monitoring equipment such as the Dranetz. This type of machine, along with an experienced electrical engineer, will reveal the most difficult to detect problems.
• Power Equipment Condition Assessments: The condition of the power distribution system is vital to the owner and the operator. Without an analysis of the condition of your electrical equipment, it is unsafe and unreliable to operate.
• Partial Discharge: This work includes data collection and analysis using Iris coupling capacitors.
• Synchronous Machines: This service provides complete testing of the main stator winding as well as the voltage drop on large rotating DC fields, diode ring, and sync-pack analysis. TDE is the only company in the Southern California area qualified and equipped to repair rotating equipment in place.

In our industry, safety is the top priority. TDE offers a variety of instructor-led, in-person safety training opportunities, including NFPA 70E: Electrical Safety in the Workplace. TDE has a fully operational training substation built onsite at our facility in the Los Angeles area. We also travel to give training at your preferred location. Training can be custom built to fulfill the specific needs of the customer.

TDE has a complete, onsite operating substation to facilitate training classes. We are the only company on the West Coast and beyond that offers this service!

Employee training is vital for electrical safe practice and proper testing. With extensive experience and superior knowledge of the NFPA, ANSI, IEEE, NETA standards, NEC and local codes, TDE offers a broad range of highly specialized, hands-on technical training at the TDE shop or customer site:

• NFPA 70E and Electrical Safety
• Hands-on Motor and Generator Training
• Hands-on Transformer Training
• Hands-on Circuit Breaker and Protective Relay Training
• Hands-on Switchgear and Motor Control Center (MCC) Troubleshooting
• Grounding and Bonding Training
