摘要： A testing finger (1) comprises a finger-shaped rod (2). A sharp end (3) of the finger-shaped rod (2) is connected with a testing part used for measuring a distance. The testing part is a group of testing heads, and the length of each testing head corresponds to minimum safe distances at different voltage levels in intrusion protection. The testing part is connected with the sharp end (3) of the finger-shaped rod (2) in a detachable insertion manner. The testing finger (1) can accurately determine whether the distance between a live part or a live lead which is not insulated in an electrical device and a protective part is greater than or equal to a minimum safety distance, thereby solving the problem in the prior art that the distance between the sharp end (3) of the finger-shaped rod (2) and the live part or the live lead cannot be accurately measured by a clamp in a situation of limited space.

摘要： The portable live line tool tester of the present invention allows high voltage to be applied to discrete segments of a live-line tool. If the tool has become conductive due to damage or contamination, a leakage meter will detect the flow of current. The tool can then be tested in increments to locate the damaged section. The invention further includes electrical safely interlock circuitry so that the tester is rendered inoperable unless it is correctly rigged and safety shielding is in place. The tester can be folded into an easily portable unit, making it unnecessary to ship tools to a laboratory for testing.
摘要翻译：本发明的便携式活线工具测试仪允许将高电压施加到活线工具的离散部分。如果工具由于损坏或污染而变得导电，则泄漏计将检测电流。然后，该工具可以增量进行测试，以确定损坏的部分。本发明还包括电安全互锁电路，使得测试仪不能操作，除非其被正确地装配并且安全屏蔽就位。测试仪可以折叠成一个便于携带的单元，无需将工具运送到实验室进行测试。

摘要： An improved apparatus is disclosed for measuring the surface insulation characteristics of coatings on magnetic materials. This apparatus comprises an insulative button block having a plurality of protruding contact buttons stationarily mounted therein, with each contact button provided with a substantially flat contact surface, and with all contact surfaces lying substantially in the same plane. The apparatus further includes a press for urging the contact surfaces against the coated surface of the magnetic material, the electric circuitry necessary to apply a predetermined voltage potential between the contact surfaces and the magnetic material, and an ammeter to measure the current flow through the coating.

摘要： An improved electrode assembly for determining the identification of metals and metal alloys having a test probe and a memory voltage indicator circuit for registering the potential difference (voltage) between the test probe and the metal to be identified. The test probe is made of a durable body having a pair of chambers therein for containing a saturated water solution of potassium chloride. A thin-walled tube is located within one of the chambers and contains therein a conductive wire and a saturated liquid mercury solution of granular calomel and potassium chloride. The voltage indicator circuit is electrically connected between the conductive wire and the metal to be identified. Utilizing the two chamber construction of the test probe substantially eliminates gas lock within the test probe and thereby allows extremely reliable and accurate readings of potential difference between the test probe and metal. These voltage readings are an indication of the characteristic properties of the metal to be identified.
