USB-8501, 1-Port, Low-Speed/Fault Tolerant, USB CAN Interface Device
786306-01
CAN Interface
The USB-8501 is a low-speed controller area network (CAN) interface for developing applications with the NI‑XNET driver. The USB‑8501 is powered over the USB bus and does not require external power. It excels in applications requiring real-time, high-speed manipulation of hundreds of CAN frames and signals such as bus monitoring, automation control, and more. The NI‑XNET device‑driven DMA engine enables the onboard processor to move CAN frames and signals between the interface and the user program without CPU interrupts, minimizing message latency and freeing host processor time for processing complex applications. The USB‑8501 is available with a three‑pin COMBICON synchronization connector for triggering and synchronizing the internal hardware timebase with other devices.

PeakTech Prüf- und Messtechnik GmbH
A Rugged sealed digital earth tester is built with all the protection you need for outdoor use. The instrument is suitable for the testing of single earth electrodes such as lightning conductors and other small earthing systems according to VDE 0413. The resistance of conductors such as continuity and conduit coupling joints can also be measured. Two-terminal operation measurement, which reduces the accuracy, can also be done by shorting P and C terminals. It has an advanced circuit design that permits the instrument to operate with the minimum influence from earth voltage and earth resistance of the auxiliary spikes.

Earth Contact Resistance Tester
-
SCR ELEKTRONIKS have developed an equipment namely Earth Contact Resistance Tester to test the appliance. To ensure the safety of operator it is essential that the Earth path (connection) should offer minimum impedance to by pass short circuit Current to Earth. This is ensured by measuring Resistance of the Earth path by passing heavy Current say 25 A. The Earth Contact Resistance Tester essentially comprises of a Variable Current source with digital Ammeter to measure the Current supplied. The Voltage drop across the Earth path is measured with a digital Voltmeter. Optionally for a particular Current (25 A) the meter can be calibrated in terms of Resistance. A timer is provided to switch off the Current after the Set Time.

Clamp-On Open-Loop DC MicroAmmeter & Insulation Fault Detector
-
The Clamp-On Open-Loop DC MicroAmmeter & Insulation Fault Detector is a precision tool designed for detecting leakage currents in insulation systems. Featuring high sensitivity, this advanced microammeter measures direct currents as low as 1 microampere (uA) and operates within a measurement range of 10 milliampere (mA) to 10 amperes (A). Utilizing a clamp-on method with a toroidal ferro-magnetic core featuring an air gap, the device integrates AMR sensors from a differential Hall magnetometer for accurate readings. Its design is particularly suitable for large hydro generator stator windings but is also effective in various electrical applications.The device's functionality is significantly enhanced by its use of two micro-ammeters equipped with advanced signal conditioning units and a demagnetization circuit, ensuring precise data acquisition. The accompanying LabVIEW software facilitates real-time monitoring and visualization of data, allowing operators to effectively track leakage currents and identify faults within insulation systems. The dual clamp-on setup enables simultaneous measurements, providing immediate insight into potential defects without the need for cutting conductors or removing insulation, thus ensuring operator safety and system integrity.
