Introduction

This procedure is based on JJF1001-2011 "General Metrology Terms and Definitions", JJF1002-2010 "National Metrology Verification rules to prepare rules "to develop. The procedures to GB/T 7261-2008 "relay protection and safety automatic device basic test method", DL/T 624- 2010 "relay protection microcomputer test device technical conditions" based on the development. This order is the first release. Test procedure for relay protection tester

1 Scope

This procedure applies to the microcomputer-based relay protection tester (hereinafter referred to as the tester) the basic functions and measurement performance of the first Sub-test, follow-up test and use of inspection.

2 terms and units of measurement

2.1 closing phase angle closingphaseangle The amount of AC excitation applied to the relay at the moment of closing, protection and safety of the automatic device voltage (or current) Phase angle. 2.2 Response time responsetime Voltage or current value from 10% to 90% or 90% to 10% of the time required.

3 Overview

Testers generally by the power supply, control part, current amplifier, voltage amplifier, auxiliary DC voltage, out Quantity, the amount of imports and other components, is the relay protection sampling accuracy, action principle, action time to test instrument. Tester control voltage amplifier, current amplifier output voltage, current, out of the output contact to the relay Protection, by the control part of the control output current, voltage amplitude, phase, frequency, open the amount of opening and closing simulation of various tests Test logic process, according to the relay protection action information and action contacts return to the tester into the amount of the situation, record the relay Protected action value and action time.

4 Measurement performance requirements

4.1 Accuracy class The tester is divided into two levels. 0.1 (where AC ± 0.1%, DC ± 0.2%) and 0.2 (where AC ± 0.2%, DC ± 0.5%). 4.2 Basic error The flow voltage is 2V U≤Umax、时间T 1s, the basic error of the tester is expressed by relative error, such as the public As shown in equation (1). γ = xx-xn xn x 100% (1) Where. γ --- the relative error of the measured value of the test instrument,%; xx --- detected test instrument display value; xn --- test standard indication.
