HV/LV POWER SOLUTIONS
ABOUT P&D SERVICES
Power & Distribution Services Ltd specialise in providing competent technical personnel to carry out engineering solutions from concept to completion in the design, supply, installation, commissioning, maintenance, inspection and integrity assurance of electrical equipment for the oil, gas, petrochemical and pharmaceutical industries worldwide.
SERVICES
Power Transformer Testing
Life expectancy of transformers are affected by various factors including;
-
Thermal influences
-
Ageing
-
Mechanical influences
-
Electrical influences
-
Protection problems
A number of reported failures have already been circulated this year via National and International Associations, which are shared across electrical authorities to enable checks to be carried out on each asset.
​
Non-intrusive tests based on IEC & IEEE can identify the internal state of transformers and provide a condition assessment of the current state of the assets.
​
Transformer Testing carried out:
-
Complete Full Visual Inspection and Data Collection of Transformer
-
Transformer Turns Ratio (TTR) Measurement
-
Short-Circuit Impedance / Leakage Reactance Measurement
-
Capacitance Power Factor / Dissipation Factor Measurement
-
Demagnetisation
-
DC Winding Resistance Measurement
-
OLTC Verification
-
Exciting Current Measurement
-
Frequency Response of Stray Losses (FRSL) Measurement
-
Sweep Frequency Response Analysis (SRFA) – Optional
Circuit Breaker Testing
Circuit breakers perform three main tasks:
​
-
When closed, they must conduct the current as effectively as possible.
-
When open, they must insulate the contacts from one another as effectively as possible.
-
In the event of a malfunction, they must disconnect the fault current as quickly and reliably as possible, thereby protecting all subsequent equipment.
In the worst case, a circuit breaker might stand still for several years, but then, in the event of a malfunction, it has to disconnect fault currents of many amps reliably within just a few millisecond. Therefore, circuit breakers need to be regularly and carefully tested.
​
Our bespoke testing solutions have revolutionised the circuit breaker testing process, as the testing solutions we offer include systems that can supply power during the testing process and are capable of measuring the micro-ohm resistance across the closed contacts.
​
Circuit Breaker Tests carried out:
-
Contact Resistance Test
-
Contact Bounce Assessments
-
Timing Tests
-
Static Contact Resistance Test (micro-ohm Measurement)
-
Coil and Monitor Current Analysis
-
Motion/Contact Travel Testing
-
Under Voltage Condition Testing
-
Minimum Pick-up Testing
Generators & Excitation
Systems
Correct preventative maintenance of Generators and associated control equipment is fundamental to a stable power distribution network. There are a number of factors which can influence the performance of such equipment.
Power & Distribution Services offer a full condition assessment which can be performed on AC Generators using the latest test equipment and reliable testing techniques, of which includes but is not limited to:
​
-
Polarization/De-Polarization Current Analysis (PDCA)
-
Measurement of Capacitance (Tan Delta)
-
Recording of Partial Discharge whilst machine is offline
-
Non-Linear Behaviour Analysis
-
Winding Resistance Measurement (IR/PI/TD)
-
Life Expectancy Analysis and Recommendations
Motors
Electric Motors are essential to running critical processes. The reliability and performance can be compromised over time when in operation as they are continually subject to the thermal, ambient, electrical and mechanical stresses.
​
Premature failure from operation wear and tear can result in production shutdowns, unexpected outages & irreparable motor damage, of which all result in significant financial losses.
​
Our complete condition assessment includes tests for:
-
Contamination
-
Insulation Degradation
-
Voltage Withstand
-
Insulation Integrity
-
Inter Turns Faults
-
High Contact Resistance
-
Connection Problems
-
Capacitance, Dissipation Factor (Tan Delta) Power Factor Measurements
