Electrical Test & Measurement

Electrical test and measurement refers to a broad range of specialised instruments designed to analyse, monitor, and troubleshoot electrical parameters within circuits, equipment, and power systems. These parameters include voltage, current, resistance, impedance, capacitance, frequency, and signal waveforms. Measuring electrical parameters is critical across industrial, commercial, and residential applications to ensure operational safety, maintain energy efficiency, comply with regulatory standards, and prevent catastrophic equipment failures or downtime.

Handheld Circuit Breaker Analyser | CAT Series

Handheld Circuit Breaker Analyser - Overview

The Handheld Circuit Breaker Analyser is ideal for use when it’s not practical to use a conventional robust circuit breaker. It is specially designed for testing circuit breakers with one break per phase. Their compact and ergonomic design can provide a wide range of features and reliable operations in low, medium, and high-voltage substations or in industrial environments. It consists of two models, the CAT-P and CAT-H. Both have a large (5,7 in) coloured touch-screen display. Test results are visible in dark places as well as in bright sunlight. The Li-Ion battery can last up to 8 hours of testing without recharging. It records: main contacts operating times, contact synchronisation, sequence time, a resistance of pre-insertion resistors, open and close coil currents, main contacts bounce time, auxiliary contact time, and DC Voltage. Multiple operations, such as Open-Close and Open-Close-Open, can be initiated by using a predefined delay time or by triggering a signal from current clamps connected to the circuit breaker coil. CAT-H is capable of performing coil control, while this feature is optional for the CAT-P. In contrast to CAT-H, the CAT-P instrument can execute the “First Trip” test. Both instruments display numerical and graphical results. A user can easily overlay up to 4 records in the graphical form and make a quick on-site analysis of potential defects. Test results can be downloaded to a PC via Bluetooth interface for more detailed analysis using DV-Win software.

Shunts | SHU-B

Shunts - Overview

Long-life shunts are used to extend the current-measuring range of moving-coil ammeters, enabling reliable display and further processing of direct currents, especially at rates up to 15 000 A. The direct current flowing through the shunt generates a proportional voltage drop which, for example, can be displayed by means of a moving coil meter connected in parallel or be further processed electronically. The shunts comply with EN 60051-1, EN IEC 60051-8 and DIN 43703. The accuracy is 0.5% relative to the nominal value. In addition, shunts with an increased accuracy of 0.2% or 0.1% can be requested. The rated currents range from 1 A to 15,000 A. Shunts are manufactured in three different designs, depending on the nominal current. Up to 25 A, the shunts are always mounted on an insulating base which can be mounted on a 35 mm DIN rail or by means of screw fixing. Above 25 A, an insulating base is optionally available for SHU-B1, as well as for some current ranges in SHU-B2.
