Content: This book mainly introduces how to measure and analyze electric charge accumulation in Dielectrics. By using the PEA and Q(t) methods with the Quantum Chemical Calculation, the charge characteristics of solid dielectrics under different situations are analyzed, which are never discussed in detail by other books. The book contains a large number of experimental and simulation data as illustrations, and thus the reader can understand the theory in the book very easily. Meanwhile, the reader can learn how to use the two methods to measure charge behavior under different conditions and analyze the charge phenomena by Quantum Chemical Calculation.

Note: Classification of charge accumulation measurement -- Fundamentals of Q(t) measurement -- Evaluation of charge accumulation -- Q(t) data of various polymer materials -- Charge accumulation in inorganic materials -- Application to insulation diagnosis -- DC Insulation and space charge accumulation -- PEA method: pulsed electro-acoustic method -- Generation of pulse pressure wave -- Basics of electrodynamics and elastic mechanics -- Examples of PEA measurement results -- Basics of Quantum Chemical Calculation -- Application examples of Quantum Chemical Calculation -- Analysis examples by Quantum Chemical Calculation.
