No. 500 -
Knopp Incorporated
The TESCO Phase Sequence Indicator meets the need for an instrument that makes basic phase sequence indication as easy as 1-2-3 (or 3-2-1). Catalog No. 500 is lighter and more compact than any other indicator available. Phase sequence is simply indicated by two neon lights. One light is for phase sequence 1-2-3 and the other light is for phase sequence 3-2-1.

No. 2J6 -
Knopp Incorporated
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.

KVTS -
Knopp Incorporated
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.

KC-1500 -
Knopp Incorporated
The Knopp Type KC-1500 Current Transformer Testing System is designed to measure the accuracy of instrument transformers having 1 and 5 ampere secondaries and primaries of up to 1500 amperes. The KC-1500 is capable of testing transformers with 1 or 5 ampere secondaries. The system uses a high accuracy multi-range current transformer as a reference standard.
-
KCTS-8000 -
Knopp Incorporated
The Knopp Current Transformer Testing System (Type KCTS-8000) is designed to measure the accuracy of instrument transformers having 1 or 5 ampere secondaries and primaries of up to 8000 amperes. The system uses a high accuracy multi-range current transformer as a reference standard. All ANSI standard burdens are included. The phase angle and ratio errors of the transformer-under-test (TUT) are measured by the built-in Knopp Automatic Transformer Comparator.

K-3, K-6, K-7 -
Knopp Incorporated
POSITIVE, STRAIGHTFORWARD SEQUENCE INDICATION IS PROVIDED over a wide variety of voltage and frequency by direction of rotor rotation. No need for range switching or terminal charging. Also indicates an open phase.
