WP-36000 -
The Eastern Specialty Company
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.

K-281 -
The Eastern Specialty Company
Knopp’s K-281 Polyphase Socket Tester is designed to detect backfeed conditions, grounds, short circuits and wiring errors in either a 120/240, 120/208 or 277/480 volt meter socket. It is equipped with high intensity Power Lights and Fault Lights to show whether or not the meter is safe to set. The Polyphase Socket Tester also comes with a heavy duty handle for quick and easy installation.

K-271, K-272, and K-273 -
The Eastern Specialty Company
Knopp’s Temporary Power Outlets are an easy and safe solution for construction sites or other areas where power is not easily accessible. The device provides temporary electric service by isolating power from the breaker panel. Easy-to-use and versatile, Knopp’s Temporary Power Outlet eliminates the need for portable generators and can be used for motor homes, travel trailers, marine shore power, construction sites, and solar pump stations. Emergency situations such as hurricane restoration, storm outages and fire damage can also utilize this device.

KVTS -
The Eastern Specialty Company
The Knopp Voltage Transformer Testing System is designed to measure the accuracy of instrument transformers having 120 volt secondaries and up to 14,400 volt primaries (special order for up to 36,000 volt primaries is available). The system includes a control console which contains the control circuitry, ANSI standard burdens, and the Knopp Automatic Transformer Comparator. The Knopp precision and loading transformer set is also included (as pictured) and is connected to the console via a special cable.

2J6 -
The Eastern Specialty Company
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.

2210 -
The Eastern Specialty Company
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).

2100 -
The Eastern Specialty Company
The TESCO Desktop Meter Station is an extremely versatile piece of testing equipment. It can be used as a programming station, a single meter evaluation station, or a test bed for checking meter features and anomalies. The newly designed Meter Station not only has the ability to simply warm-up meters, but also has optional features such as an external load (1PH) or an internal phantom load (0.5A), an optional disconnect operation (1000VA XFMR), a load receptacle, or a tilt chassis. For easy operation, all options are conveniently mounted on the front panel.
