Riviera's Testing Capabilities
- True RMS Voltage and Current Testing: Capture and record the square root
of the average square of the instantaneous magnitude of the voltage
and current. This test is used to determine if the correct voltage
and current is present to properly operate your equipment and
optimize its life cycle.
- Voltage Drop Testing: Utilize true RMS voltage readings found in the
above test to calculate voltage drop. This test is used to determine
if the electrical components, i.e., circuit breakers, contact
surfaces, etc., are operating properly to reduce hazards and equipment.
- Thermographic Testing: Measure and record to identify temperatures
that exceed NETA section 9.5 and NFPA 70B-1994 Section 18-16,
i.e., high resistance electrical connections, current overload,
defective circuit breakers, and/or defective insulator conditions.
The tests shall be performed using a FLIR Prism DS Camera. This
test is used to reduce the risk of brownouts and blackouts, as
well as safety and fire hazards.
- Ultrasonic Testing: Measure and record sound waves and/or vibrations
that are above the audible sound level (16-18kHz). The tests shall
be performed using a UP2000 Detection System. This test is used
to complement the Thermographic Testing and determine if corona
discharge, tracking, arcing, and vibration are present and to
assure the quality and integrity of the electrical system.
- Harmonics Testing of Voltage and Current:
Measure and record the total harmonic distortion, voltage (THDV)
and total harmonic distortion, current (THDC) that exceed "IEEE
519 A Guide for Harmonic Control and Reactive Compensation of
Static Power Converters". The tests shall be performed using
FLUKE 41, 87, 99 Testers. This test is used to determine if harmonic
contaminations are within tolerance levels. In addition, this
test is designed to assure accurate power (kW) charges and to
minimize the risk of damage to microelectronic equipment, transformers,
circuit breakers, motors, etc.
- Power Factor Testing: Measure and record the
ratio of the circuit power (watts) to the circuit volt-amperes.
This test is used to determine if increased costs are being paid
to the utility company because the power factor is in a higher
rate schedule. In addition, correcting a poor power factor situation
may allow expansion of the electrical systems capacity without
costly system additions.
- Crest Factor Testing: Measure and record the reaction of the peak
voltage value and average voltage value. This test is used to
assure that power quality, including harmonic distortion, is within
safe operating limits.
- Visual and Mechanical Inspections: Interior and exterior of all
components shall be inspected to ascertain and, if necessary,
make certain adjustments to ensure that its performance remains
within specified limits. Also identify corrosion, rust and discoloration,
leaks, safety hazards, National Electric Code violations, grounding,
physical damage, and the general condition of components.
- Phase-Balance Testing: Test to assure that
the phases in the electrical system are balanced. This test is
used to address unbalanced components that increase power-quality
problems, total harmonic distortion, as well as increased temperature
rise of devices and current-carrying conductors.
- Insulation Resistance Testing: Measure and record the resistance
of insulation under specified conditions set forth by manufacturer
or NETA Acceptance Testing Specification 1995. This test is designed
to assure that the electrical system and components and the insulation
values are at an acceptable level, reducing the risk of explosions,
fires, and catastrophic breakdowns.
- Winding Resistance Testing: Measure, record
and compare the winding resistance of components. This test will
assure that components are operating to manufacturer's specifications,
extending useful life, and reducing the risk of catastrophic failure.
- Contact Resistance Testing: Measure and record
the resistance present between contact surfaces. This test addresses
poor contact surfaces that would cause increased voltage drop,
increased heat and reduced life expectancy, causing brown-outs,
black-outs, explosions, fires, and catastrophic failures.
- Circuit Breaker Testing (Low Voltage): Measure, record, and document
all appropriate testing required by NETA Section 7.6. The proper
testing and inspection of circuit breakers will reduce the risk
of business interruption, fire, and catastrophic failures.
- Ground Resistance Testing: Measure and record the resistance of conductors,
connections, and devices. This test will reduce the risk of power
quality, harmonic, and safety issues.
- Transformer Testing: Measure, record, and
monitor, all appropriate testing and inspection to manufacturer
recommendations and/or NETA 1995 Acceptance Testing Specifications.
This testing and inspection is performed to reduce the risk of
transformer failure, which could result in fire, and/or catastrophic
failures.
- Visual and Mechanical Inspection: Interior and exterior of all components
will be inspected to ascertain and, if necessary, make certain
adjustments to ensure that its performance remains within specified
limits. Vendor must also identify corrosion, rust, and discoloration,
leaks, safety hazards, Nation Electric Code violations, grounding,
physical damage, and the general condition of components.
