TESCO’s Service Ground Test Set has been designed to check the condition of the ground connection on a secondary service. If for any reason the ground connection has a resistance, this can be immediately detected by the Test Set. The Service Ground Test Set consists of a voltmeter which can be shunted by a resistance of 60 ohms. The voltmeter is of the suppressed zero type with a double range, from 65 to 130 or from 130 to 260, and can be used for checking service voltage independently of the ground test.

The Eastern Specialty Company
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.

BSC-102 -
The Eastern Specialty Company
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.

Voltage and Current -
The Eastern Specialty Company
Testing and calibrating instrument transformers often requires standard burdens of reliable accuracy and stability, and burdens that are immune to stray fields and harmonics. The burden sets described below have been carefully designed to meet these requirements.
-
KCTS-8000 -
The Eastern Specialty Company
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.

IEC Burden Sets -
The Eastern Specialty Company
Testing and calibrating current transformers often requires standard burdens of reliable accuracy and stability, and burdens that are immune to stray fields and harmonics. These burden sets have been carefully designed to meet these requirements. They also provide the standard burdens required for the testing of current transformers for metering service, and for the testing (within the current rating provided by the sets) of current transformers for relaying applications, all as called for by IEC (International Electrotechnical Commission) Publication 185: 1987.

4E2-1 -
The Eastern Specialty Company
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.

P-5000 -
The Eastern Specialty Company
The P-5000 transformer is a laboratory standard. The unit’s excellent accuracy and the Knopp One-to-One calibrating feature make this precision transformer well-suited as a standard for calibration work. This transformer can provide a very accurate determination of the ratio and phase angle characteristics of current instrument transformers having ratios from 5 to 5,000 amperes. This transformer also can accurately extend the range of a 5 ampere ammeter or wattmeter to cover all current values up to 5,000 amperes.
