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.

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.

Hilo Test
Surge pulses occur due to direct or indirect lightning strikes in a circuit or by switching transients caused by switching inductive loads or short circuits. This leads to currents or electromagnetic fields causing high voltage or current transients. Surge voltages and currents can reach several thousands of volts and thousands of amperes. Our following Surge generators simulate these disturbances for all the necessary level in accordance with IEC / EN 61000-4-5 and IEC / EN 60060.

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.

Hubbell Power Systems Inc
Next to your people, your power grid infrastructure is your largest and most valuable investment. Protect it with Hubbell Power Systems, Inc. surge arresters. Every lightning strike, insulator flashover and switching surge adds wear and tear to your equipment, prematurely aging it, and requiring you to shoulder the costs of replacement. Even the smallest surge can shorten your equipment’s life. Surge arresters, however, extend the life of your system by limiting the voltage across your equipment during a surge event.

Smiths Interconnect
Filter connector series includes EMI/ EMP/ESD circular, ARINC, D-subminiature and micro-D connector styles. They can be combined with high energy TVS diode technology to achieve lightning and EMP transient protection. Smiths Interconnect's EMI filter connectors use multi-layer ceramic capacitor arrays together with inductive materials to realize robust, high performance low pass filter networks. Where required, transient protection can be combined with EMI /RFI filtering to provide maximum protection. The diodes as well as the EMI filter are packaged separately so the construction of the connector remains modular.

ROSS ENGINEERING CORPORATION
These supply 120V or 240V AC continuous power for equipment that must operate while at a high voltage to ground or power source. For example, a fiber optic transmitter at the HV level for waveforms to be received and measured or recorded by grounded instrumentation might be powered by an isolation transformer secondary to primary either insulated by potting, oil or air. The low dielectric constant of air insulation provides lower capacitive coupling between the secondary and the primary or ground than would solid or oil insulation. The lower capacitance provides better isolation both at line frequency and especially at high frequency voltages such as lightning or switching transients.
