What is PD IEC/TS 60815-4 – Insulators for d.c. systems about?
PD IEC/TS 60815-4 is a Technical Specification, that is applicable as first approach for the determination of the required d.c. Unified Specific Creepage Distance for insulators with respect to pollution. To avoid excessive over or under design, existing operation experience should be compared and eventually additional appropriate tests may be performed by agreement between supplier and customer. It is applicable to:
- Glass and porcelain insulators
- Composite and hybrid insulators with an HTM or non-HTM housing
PD IEC/TS 60815-4 is the fourth part of the multi-series that gives specific guidelines and principles to arrive at an informed judgment on the probable behavior of a given insulator in certain pollution environments.
PD IEC/TS 60815-4 is applicable to :
- Glass and porcelain insulators
- Composite and hybrid insulators with an HTM or non-HTM housing

Why should you use PD IEC/TS 60815-4 - Insulators for d.c. systems?
PD IEC/TS 60815-4 gives specific guidelines and principles to arrive at an informed judgement on the probable behaviour of a given insulator in certain pollution environments.
PD IEC/TS 60815-4 aims to give the user simplified means to:
- Identify issues specific to d.c. applications that can affect the choice and design process
- Determine the equivalent d.c. Site Pollution Severity (SPS) from measurements, correcting for electrostatic effects, diameter, pollution distribution, and composition
- Determine the reference USCD for different candidate insulating solutions, taking into
- account materials, dimensions, and risk factors
- Evaluate the suitability of different insulator profiles
- Discuss the appropriate methods to verify the performance of the selected insulators
Thus, PD IEC/TS 60815-4 can ensure insulators for d.c systems are fit for its intended purpose.
