Frequently asked questions
How do I choose a multimeter for industrial electrical maintenance?
Three parameters matter: the measuring range (AC/DC voltage, current, resistance) must cover the values in the installation being checked; the resolution and accuracy stated by the manufacturer decide how fine the differences you can distinguish are; and the safety category (CAT III or CAT IV, according to IEC 61010) must match the measurement point in the installation - a CAT III multimeter is suitable for distribution panels, CAT IV for the point of connection to the network. Additional functions useful in maintenance are measuring inrush currents, a continuity test with an audible signal and storing values for reporting.
What does the CAT III / CAT IV safety category mean for a multimeter or a tester?
The overvoltage categories defined in IEC 61010 show how close to the energy source the measurement is made and what level of transients the instrument can withstand without risk to the user. CAT II covers sockets and equipment connected to the final circuit, CAT III the distribution circuits in industrial panels and fixed machinery, and CAT IV the origin of the installation - the service connection from the distribution network. An instrument with a lower category used at a point with a higher category does not offer sufficient protection against an electric arc or a transient overvoltage. Choose the category for the riskiest measurement point in your work, not for the most frequent one.
What PRAM checks must be done periodically and what instruments are needed?
Periodic electrical safety checks (PRAM) include measuring insulation resistance and earth resistance, testing the continuity of the protective conductor and checking the operation of residual current devices, according to the standards applicable to measuring instruments (for example IEC 61557). For low-voltage electrical installations an installation tester (insulation, earthing, RCD) is needed and, for more complex networks, equipment for testing protection relays and locating cable faults. The frequency of checks and the documents required depend on the type of installation and on the internal regulations of the beneficiary or of the authority that accepts the report.
How do I choose a thermal imaging camera for predictive maintenance?
Thermal resolution (the number of pixels of the sensor) determines how small the details visible in a thermographic image are, and thermal sensitivity (NETD, expressed in millikelvin) shows the smallest temperature difference the camera can distinguish - essential for detecting an incipient hot spot at an electrical connection. The measurable temperature range must be chosen according to the application: electrical, mechanical or process checks have different ranges. For predictive maintenance reports, the analysis software supplied with the instrument also matters, as it allows critical points to be marked and their evolution over time to be tracked.
What is a power quality analyser and when is one needed?
A power quality analyser measures the parameters of the electrical network - voltage, current, power factor, harmonics, phase imbalance and events such as sags or overvoltages - and records them over a period of time (logger) for later analysis. It is needed when problems arise that are hard to explain with spot measurements alone: repeated tripping of protections, overheating of equipment, energy bills that do not match the expected consumption, or the energy audit of an industrial hall. The choice of model depends on the number of phases monitored, the accuracy class required and the length of recording needed for a relevant diagnosis.
What do I need to send for a quote on test and measurement instruments, and how long does delivery take?
The most useful information is: the type of instrument or the parameter to be measured, the measuring range required, the CAT safety category required by the application and whether a calibration certificate is needed on delivery. For process equipment (analysers, loggers, calibrators) the number of channels or phases monitored also matters. The lead time is 24–72 h when the item is available locally or at the supplier; to order, usually 1–4 weeks; it may take longer depending on the brand and the specifications. The calibration certificate, when requested, may add extra time because the check is carried out by the manufacturer or by an accredited laboratory before dispatch.
