How We Deliver MET Service®
First, we take an inventory of all the electrical components to be tested, starting with the most critical ones such as your main switchboard and the supply to any vital piece of equipment such as your server room, and then work through your complete facility.
Following your free electrical distribution audit we discuss what is to be tested and when within the 3-year cycle you want it carried out.
A digital reference image and thermal image is taken for each individual component as well as issuing a unique reference number in the software. To this, the full component name plate data is recorded, enabling quick reference for site location and spares ordering through the asset management software’s search facility.
We then work through each switch board, distribution board, motor control panel, UPS systems, fuse board, isolator and any other components connected to your equipment to be tested.
We carry out a wide range of electrical tests to suit your individual facility and budget, which can include Periodic Test and Inspection (EICR) as well as MET Service® to give you the best level of testing available and complete peace of mind that if we pass your system, we take on the responsibility for labour costs for the length of your agreement with us.
MET Service® Preventative Maintenance Programme is recommended to be performed annually, and while the facilities electrical distribution system is energised under normal load. Typical tests performed are:
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 service is used to determine if the correct voltage and current is present to properly operate the Owner’s equipment and optimise its life cycle.
Measure and record the difference of voltages at the two terminals of passive impedance.This service is used to determine if your electrical components, i.e., circuit breakers, contact surfaces, etc., are operating properly to reduce hazards and equipment destruction.
Infrared Thermographic Imaging Service:
Measure and record to identify temperatures that exceed the manufacturers recommendations. High resistance electrical connections, current overload, defective circuit breakers and/or defective insulator conditions.This service is used to reduce the risk of component failure, as well as safety and fire hazards.
Measure and record sound waves and/or vibrations that are above audible sound (16-18 KHZ). This service is used to complement the thermographic imaging service and determine if corona discharge, tracking, arcing and vibration are present, and to assure the quality and integrity of your electrical system.
Voltage and Current Harmonics Testing:
Capture and record Total Harmonic Distortion-Voltage (THDV) and Total Harmonic Distortion-Current (THDC) that exceed IET recommendations.This service is used to determine if your harmonic contamination is within tolerance levels.In addition, this service is designed to assure accurate power (kW) charges and to minimise 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 service is used to determine if you are paying increased costs to their utility company because your power factor is in a higher rate schedule. In addition, correcting a poor power factor situation may allow you to expand your electrical system’s capacity without costly system additions.
Visual and Mechanical Inspections:
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.The Contractor will also identify corrosion, rust and discoloration, leaks, safety hazards, applicable electric code violations, grounding, physical damage and the general condition of components.
Assure that the phases in your electrical system are balanced.This service 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.
