What is a Capacitance Meter?
Capacitance Meter Definition
A capacitance meter is a device used to measure the capacitance of discrete capacitors.
Working Principle
It operates based on the proportional relationship between capacitance and a time constant.
Measurement Method
Capacitance is measured using a 555 timer by calculating the time period of oscillations.
Role of 555 Timer
The 555 timer acts as an astable multivibrator, with its frequency determined by the unknown capacitance (CX).
Practical Use
Proper shielding of leads is necessary to avoid instability in low capacity measurements.

Why Regular Transformer Maintenance Matters: 5 Serious Consequences of Neglecting It
I. Allowable TemperatureWhen a transformer is in operation, its windings and iron core generate copper loss and iron loss. These losses are converted into heat energy, causing the temperature of the transformer's iron core and windings to rise. If the temperature exceeds the allowable value for a long time, the insulation will gradually lose its mechanical elasticity and age.The temperature of each part of the transformer during operation is different: the winding temperature is the highest, fol

How to Implement Condition-Based Maintenance for Power Transformers? A Complete 4-Step Process Analysis
1. Definition of Condition-Based MaintenanceCondition-based maintenance refers to a maintenance method where decisions on whether and how to perform maintenance are determined based on the real-time operating status and health condition of equipment. It has no fixed maintenance methods or schedules. The prerequisite for condition-based maintenance is the establishment of equipment parameters and the comprehensive analysis of various operational information of the equipment, so as to make reasona

Traction Rectifier TransformersRated capacity: 800 to 4400 kVA; Voltage class: 10 kV and 35 kV; Rectifier pulse number: 12-pulse and 24-pulse. Compared with 12-pulse rectifier circuits, 24-pulse rectifier circuits can reduce the harmonic pollution of the power grid by 50%, and no filtering equipment is needed at this location. It is suitable for power supply systems of urban subways and rail transit.Excitation Rectifier TransformersRated capacity: 315 to 3000 × 3 kVA; Voltage class: 10 kV, 13.8

High harmonics? Your transformer may be overheating and aging fast.
This report is based on the analysis of one-day power quality monitoring data of your company's distribution system. The data shows that there is significant three-phase current harmonic distortion in the system (with a high total harmonic distortion of current, THDi). In accordance with international standards (IEC/IEEE), harmonic currents at this level have posed substantial risks to the safe, reliable, and economical operation of the power supply transformer, mainly manifested in additional h
