ELTEL INDUSTRIES CALIBRATION LABORATORY

NABL ACCREDITED

NABL ACCREDITEDELTEL INDUSTRIES - CALIBRATION LABORATORY

The Eltel Industries - Calibration Lab is equipped with

customized world class standards to calibrate

instruments designed for use by transformer

manufacturers and power utilities.

Eltel Industries, being a manufacturer, has a deep

technical understanding of calibration requirements.

The advantage of getting the equipment calibrated at

our Calibration Lab is the assurance that the calibration

charges will be appropriate for the entire range rather

than for specific calibration points. Eltel Industries takes

pride in offering calibration services on par with

International Standards - we look forward to working

with you.

The laboratory is now open for performing calibration activities with the following unique standards on board. • Precision Current Transformer with accuracy of

0.002% and best CMC of 60 PPM.• CVRPS -2013 to calibrate Instrument Transformer

Test Sets for both Ratio Error and Phase error(Direct method).

• Power analyzer to calibrate Current transformer burdens and Voltage Transformer burden.

• Capacitance & Tan Delta Standard up to 10 kV.• High Resistance Standards (1kΩ to 10 TΩ). • Low Resistance Standards (1mΩ to 1 KΩ). • Fluke 5080 A Calibrator. • Fluke 8846A 6½ Digit Multimeter.

We are pleased to announce the NABL accreditation of the Eltel Industries- Calibration Laboratory in Electro - technical discipline in accordance to ISO/ IEC:17025/2005.

PRECISION CURRENT TRANSFORMER CALIBRATION SET UP

CURRENT & VOLTAGE TRANSFORMER RATIO AND PHASE ERROR STANDARD – CVRPS 2013

AUTOMATIC INSTRUMENT TRANSFORMER TEST SET - AITTS 98

2

PRECISION CURRENT TRANSFORMER (20 PPM)

The precision Current Transformer along with

7200A High Current source covers ratios from

5A/ 5A : 5A / 1A all the way upto 6000A/ 5A :

6000/1A with best overall uncertainty of 60 PPM

– which is on par with the best calibration

laboratories. The ratio range provided covers

all typically manufactured standard and

commercial grade Current Transformers.

The CVRPS generates fixed Ratio and Phase

Errors that enable the calibration of Instrument

Current Transformer Test Sets and Instrument

Voltage Transformer Test Sets using Direct

Method. This unique standard allows the

calibration of test equipments at different

ranges of Ratio and Phase Errors. This facility is

unique to the Eltel Industries – Calibration

Laboratory and to the best of our knowledge,

is not currently available in any other NABL

accredited labs. The best uncertainty of

80 ppm, 0.4 min is class leading and best

available in the Industry.

This is a high accuracy comparator

manufactured by Eltel Industries. This is used to

calibrate Current Transformers and Voltage

Transformers for Ratio Error & Phase Error. It has a

best uncertainty of 55 PPM.

TRANSFORMER RATIO STANDARD - TRS 5000

HIGH RESISTANCE STANDARD

CAPACITANCE & TAN DELTA STANDARD SET UP

3

This standard set up comprises of a SF6 filled

Standard Capacitor, a Step down Voltage

Transformer (11kV/ 110 V) & Dissipation Factor

Error Standard. The Standard is capable of

introducing Tan Delta from 0% to 10%. Using this

standard set up, the Capacitance & Tan Delta

Test Sets can be calibrated up to 10 kV. The best

uncertainty 0.3% for Capacitance & 0.02% for

Tan Delta.

This is a Precision Turns Ratio Standard

developed by Eltel Industries for their Calibration

Laboratory. It has a Ratio Range from 1/1 to

5,000/1. Used for calibration of manual and

Automatic Single and Three phase Transformer

Ratio Meters. The accuracy is better than 0.01%

over the entire range.

This High Resistance Standard is manufactured

by an Industry pioneer and offers resistance

ranges from 1KΩ to 10 TΩ. It is used to calibrate

High Resistance Insulation Test Sets, Tan Delta

and Resistivity Test Sets.

5080A MULTI PRODUCT CALIBRATOR

6½ DIGIT PRECISION MULTIMETER

LOW RESISTANCE STANDARD

DIGITAL POWER ANALYZER - WT210

This set of Precision Low and Medium Resistance

Standards is from a leading Resistance

manufacturer of discrete standards. We have a

best uncertainty of 0.02% ranging from 1milliΩ

to 1kΩ. They are used to calibrate low resistance

Ohm Meters, Transformers Winding Resistance

Meters.

The Power analyzer with a best uncertainty

of 0.37% is used for calibrating Current

Transformer Burdens and Voltage

Transformer Burdens.

This is a Fluke Universal 5½ digit Calibrator

and has the highest compliance with

maximum burden up to 800 milli amps for

AC and DC voltages and a voltage up to

50V for AC and DC currents. This unit is used

to calibrate Multimeters and also used as a

AC Current and Voltage source.

This Fluke Standard Meter is capable of

calibrating any 5½ digit calibrators. It is also

used to calibrate any AC, DC current and

Voltage Sources and Resistances.
