T/TBPS 4002-2017 Anti-interference AC Voltage Regulator Technical Specifications and Measurement Methods
Basic Information
Scope
This standard specifies the terms, technical requirements, and measurement methods for AC voltage stabilizers with anti-interference functions. This standard applies to anti-interference AC voltage stabilizers with single-phase or three-phase AC input and single-phase or three-phase AC output (hereinafter referred to as "power supplies"). This standard does not apply to AC calibrators used for measurement purposes. This standard adjusts the applicable content of SJ/T10541-1994 "General Technical Conditions for Anti-Interference AC Voltage Stabilizers" and SJ/T10542-1994 "Test Methods for Anti-Interference AC Voltage Stabilizers". The main changes are as follows: - Added general terms in this standard: apparent power (see 3.1.1), active power (see 3.1.2), reactive power (see 3.1.3), load power factor (see 3.14), and load-carrying capacity (see 3.15). - Added the load-carrying capacity classification of power supplies (see 4.8.1 Table 2). - Added the calculation formula and measurement method for pulse load power factor (see 4.8.1). - Specified the lower limit value for MTBF (Mean Time Between Failures): MT <
