National Technical Systems
The indirect effects of lightning are caused primarily by earth-voltage rises that occur when the flash dumps charge into the earth and by the intense electromagnetic field associated with the flash. These fields and earth-voltage rises have enough energy to cause component damage up to a kilometer or more from the actual strike. Indirect effects are most commonly induced into system interconnecting cables and may damage or upset electronic components.

WERA -
ASL Environmental Sciences
The WERA system (WavE RAdar) is a shore based remote sensing system using the over the horizon radar technology to monitor ocean surface currents, waves and wind direction (Gurgel, 1999). This long range, high resolution monitoring system operates with radio frequencies between 4 and 50 MHz. A vertical polarized electromagnetic wave is coupled to the conductive ocean surface and follows the curvature of the earth.

M151 -
Clarke-Hess Communications Research
The Model M151 is a stable high current calibrator up to 120 A. Basic accuracy is 0.035 %. It can be controlled viaRS232 or GPIB interface. The Model 151 can function in a simulated amplifier mode to increase the current capabilityof any multifunction calibrator. It is suitable for power meter calibration because it can be synchronized with the inputsignal not only in amplitude but also in frequency and phase. The current terminals are isolated up to 450 Vpk againstcase (protective earth).

ZGC -
Alpha Lab, Inc.
The model ZGC zero gauss chamber reduces the environmental magnetic field (Earth field) to near zero inside the chamber. Any gaussmeter probe which is less than 9.4 mm or 0.370" diameter can be placed inside. The meter is then "zeroed", which means that it will read zero whenever the probe is subsequently placed in zero field. By using a zero gauss chamber, any offset error is therefore eliminated. The model ZGC is unique in that it contains a degausser (demagnetizer). This is situated between the inner and outer mu-metal shields. When the degauss button is pressed, any accidental magnetization of the chamber, no matter how strong, is erased. Accidental magnetization is a major problem with most zero gauss chambers and it has limited their use. If a magnet comes too close, the chamber will become "permanently" magnetized and will have an internal field that is typically 0.2 to 0.5 gauss. The chamber must then be degaussed because the Earth field is also around 0.5 gauss, so a magnetized zero gauss chamber will not significantly reduce the field.

Model 273 HP -
Kusam Electrical Industries Limited
The 273 HP is a Non-contact voltage detector. It has two ranges for selection.The 273 HP consists of an internal pickup sensor, a function selection switch, a visual and a sound annunciator. With the 273 HP, physical contact with electrical conductors is not necessary when testing for live lines. Its sensor senses the radiated field which surrounds live conductors. Radiated field strength increases with voltage and decreases quickly with distance or earth shielding
