Third Rail Voltage Tester
4E2-1
-
The Knopp 4E2-1 Voltage Tester is designed to detect electrical potential (voltage) between the third rail and ground on high voltage electrified transit systems. Two, redundant neon bulbs are used to indicate the presence of voltage. The prod handle and the tester housing are both made from moisture- and oil-resistant laminated phenolic. The prod tips are made from stainless steel. The tester housing includes a rubber hand guard to guide the operator in proper placement of his or her hand. There are no exposed metal parts other than to the two prod tips. All internal connections are soldered.

Desktop Test Interface Station
2210
-
TESCO’s new Desktop Test Interface Station (Catalog No. 2210) provides metering professionals with exceptional testing flexibility. The Test Interface Station is ergonomically designed for meter technicians working in a lab or a desktop, yet still rugged for field use. The Test Interface Station includes a zero insertion force (ZIF) meter socket, voltage selection, form selection, open/closed-link selection and bi-directional cabling to power a load box/test kit & connect test standard potentials. When combined with a test kit/test standard and powered via 120 VAC, the Test Interface Station creates a single position, stand-alone, meter accuracy testing device for various socket based meters (both mechanical & solid-state).

CT/PT Bus-Bar Safety Protector
6450
-
The TESCO CT/PT Bus-Bar Safety Protector (Catalog No. 6450) has been developed to assist in the safe disconnect of a hot sequenced current transformer. After service is disconnected, the TESCO CT/PT Bus-Bar Safety Protector is slid over the bus-bar of the load side of the transformer and prevents accidental connection and/or arcing.

Burden Set – Current
BSC-102
-
The industry has recognized the actual load (burden) on CTs is lower than the standard ANSI burdens allow. So a new IEEE Specification (IEEE C57.13.6) accommodates that fact by introducing two new burdens and two new accuracy classes. This new specification address “High Accuracy”CTs.

Uniload Voltage Transformer Test Set
2J6
-
The Type 2J6 Knopp Uniload Voltage Transformer Test Set consists of three major parts: When the Knopp Precision Transformer in the 2J6 set is compensated for, and used with, a secondary burden of 15 volt-amperes, for example, the ratio of this precision transformer is well within 0.02% and the phase angle is well within 2 minutes. The transformer, in common with other Knopp Precision Multirange Transformers, is wound so that it has practically the same ratio and phase angle accuracy on all ranges.

Meter Test Switches
-
TESCO introduced the original Meter Test Switch in the early 1920’s. Today, TESCO’s line of Test Switches has been redesigned with the intention to combine the best features of tried and proven switching methods with improvements in materials and construction. All of the current carrying parts are bright tin plated to prevent corrosion. Good operating contact is assured on periodic meter tests, even when the switch has been idle for long periods of time in an unfavorable atmosphere.

Total Energy System
5000
-
The electric vehicle (EV) charging market is rapidly expanding, with more and more people switching to electric cars. As the demand for EV charging stations increases, so does the amount of energy that is being exchanged. This energy exchange market is already massive, with charging peaks reaching into the megawatts of energy. With this amount of energy comes a significant amount of revenue, which requires the most accurate billing possible. That’s where TESCO’s Catalog No. 5000 – Total Energy System comes in. The Catalog No. 5000 is a double duo system that enables the testing and accuracy verification of Electric Vehicle Service Equipment (EVSE) and Field Test Equipment for testing EVSE’s in the field. This system is a dual-purpose DC and AC System and includes both a 100A AC (ACT-100) Test System and a 200A DC Test System (DCT-200).

Precision Multirange Voltage Transformers
WP-36000
-
The WP-36000 Transformer is primarily a laboratory standard. The high degree of accuracy and multiplicity of ranges makes this transformer the standard for precision calibration work. With the aid of this transformer, very accurate determination can be made of the ratio and phase angle characteristics of voltage transformers having ratings from 14,400 to 36,000 volts.
