The precision clip-on CT’s has been designed for the measurements of currents in the range of 100 mA up to 1000 A. Their small size makes them particularly handy when working in cramped spaces such as meter installations or circuit breaker boards. 1000 A measurement, excellent metrology, high accuracy, height level of linearity, symmetrical coil windings for minimum phase shift, pendular adjusting system for magnetic elements, maxi- mum conductor diameter Ø 52 mm Innovative design, ergonomic shape, handle with finger grips, assisted opening system for jaws (patented system). Safety standards IEC 1010 600, V CAT III (in- dustry and services), anti-slipping protection, conductor anti-pinching system, etc. All this unparalleled technology and quality of manufacturing to get the best measurement possible without any complications. The precision clip-on CT’s are compatible with MTE’s test equipment to measure perfectly any AC currents, both safely and without breaking the circuit. Download the Catalog

Flexible Current Transformers The flexible current transformers FLEX 3000 ensure safe, accurate and non-intrusive measurements in applications that may be completely inaccessible with conventional current clamps and probes. The probes provide a linear voltage output that is an exact replica of the input waveform for three user selectable input current ranges of 30, 300 or 3000 Amperes. The standard 610 mm flexible conductor allows a measuring diameter of up to 194 mm. Advantages • Ideal for large and hard to reach conductors • Flexible and lightweight, less than a quarter of the weight of conventional CTs • No restrictions with regard to duty cycle or overload current • Selectable current ranges of 30/300/3000A • AC coupled mV output proportional to measured current • Accuracy: Ein + Em Ein: Accuracy of instrument input Em: Accuracy specified by manufacturer Basic specifications for 45 Hz … 65 Hz: Accuracy: ± 1 % of range Phase error: < ± 1° Position sensitivity: ± 2 % of reading Download Catalog

Sensors for measurements on high voltage and current potential The LiteWire sensors are suitable for MTE’s meter test equipment PRS 400.3 and PTT 2.1. The LiteWire is a true RMS meter designed for use by electric utilities to sense currents or volt- age waveforms from the primary side of their distribution networks. A fiber optic link transmits information as well as establishes isolation between the high voltage potential at the sensor enclosure. The sensors are mounted on a hot stick and slipped over a high voltage line. A fibre-optical cable connects the sensors to a receiver unit at ground potential. This receiver contains the digital readout and an analogue output. Download the Catalog
