Shanghai Jiuzhi Electric Co., Ltd.
Our advanced CDY series Impulse test systems are used for impulse voltage testing of transformers, cables, gas-insulated switchgears (GIS), arresters, and other high-voltage devices. The test systems generate lightning impulse voltage (LI, 1.2/50 µs), chopping lightning impulse voltages (LIC, front time 1.2 µs, front, crest or tail chopped), and switching impulse voltage (SI, 250/2500 µs) in accordance with IEC 60060-1; as well as IEC 60076-3 for transformers, and IEC 62067, 60840 and 60502-1 for cables). By adding extra components, our impulse test system also can generate steeping wave (SWI, >2500kV/ µs) and impulse current (IC, 4/10 µs, 8/20µs, 10/350µs).

Hilo Test
Ring wave or oscillatory wave are pulsed onset, damped oscillatory waves as it can be but triggered in low-, medium- and high-voltage systems in data networks as a noise voltage by switching operations, lightning strikes and insulation breakthroughs in cable runs. The Ringwave Immunity tests for electrical equipment are described in the basic EMC standards.

AS-RXFEP RX -
Array Solutions
The AS-RXFEP Receiver protector limits input RF signal threshold from 1 to 150MHz to less than 0.3 Vrms to protect a receiver front end from damage due to nearby transmitted signals. The receiver still actsnormally and measured signal strength is not affected.The circuit uses a multi-stage design of transformer saturation coupling and current limiters. It also incorporates a low voltage GDT to protect from lightning events. These are for receiving only - you cannot transmit through them without damaging the unit.

Weshine Electric Manufacturing Co., Ltd
High-voltage Dividers (High Potential Divider) are used to measure voltages and decouple partial discharges in high-voltage test systems. Depending on the specific type, they are used to measure alternating voltage (AC), direct voltage (DC), lightning impulse voltage (LI), and switching impulse voltage (SI) systems. High-voltage dividers by HIGHVOLT comply with the relevant IEC standards. The systems are available for both indoor and outdoor use.

Fivestar HV Testing Equipment Co., Ltd.
Impulse current test systems are mainly used for testing transmission and distribution systems against the effects of direct or indirect lightning strokes or against electromagnetic interference effects. Primary application of impulse current test systems is the testing of surge arresters, nowadays mainly of the metal-oxide type (MOA) and surge protection devices (SPD). Now they are also widely used to test vehicles, aircrafts, and military applications.

InfiniteFocus -
Alicona Imaging GmbH
With the InfiniteFocus you benefit from a 3D micro coordinate measurement machine and surface roughness measurement device in only one system. The range of measurable surfaces is almost unlimited, enabled by the use of coaxial lightning and optimized LED ring light. You achieve traceable measurements that combine high resolution, high repeatability and high accuracy. All relevant surface features are measured using only one multi-functional measurement sensor. Generally, the optimal setting of measurement parameters is provided automatically. This allows multiple users in different groups or departments with different materials to use the system with ease and confidence.

Georg Fischer Signet
The Signet 2540 Paddlewheel Flow Sensor offers field-replaceable electronics and transient voltage suppression (TVS) to provide greater immunity to large voltage disturbances (i.e. lightning) sometimes encountered in field wiring. Sensors can be installed in DN40 to DN600 (1 to 24 in.) pipes using the 1 inch NPT or ISO 7/1-R 1.5 threaded process connection. The sensors are also offered in a hot-tap configuration with a bleed valve service without process shutdown in pipes up to DN900 (36 in.). Both styles of sensors must be used in full pipes and can be used in low pressure systems.

Mors Smitt Group
Operating records for overhead power lines reveal that most faults are of a transient nature (e.g. lightning induced) & that service interruptions may be minimized by use of automatic reclosing of circuit breakers. An automatic reclosure of the circuit breaker, after the fault clears, provides improved service continuity & system stability. The 1B230 Series Reclose Relay provides for single or double shot automatic reclosing of circuit breakers, following interruption of supply due to a fault in the system.
