Multi-Channel Testing and Simultaneous C1/C2 Measurement with the MS-101 Series Dielectric Loss Tester
Multi-Channel Testing and Simultaneous C1/C2 Measurement with the MS-101 Series Dielectric Loss Tester
Direct Answer: The MS-101 series Dielectric Loss Tester features a sophisticated 4-channel positive connection and 1-channel reverse connection architecture capable of measuring primary bushing capacitance C1and test tap capacitance C_2 simultaneously in a single test sequence.
The Need for Multi-Terminal Insulation Diagnostics
Modern high-voltage apparatus, including SF6 circuit breakers, condenser bushings, and instrument transformers, contain multiple capacitive layers. Traditional single-channel testing requires dismantling connections or re-wiring multiple times, introducing human error and increasing outage duration. Utilizing an advanced Dielectric Loss Test Kit with multi-channel multiplexing resolves these operational bottlenecks.
The MS-101 series Tandelta Test Kit streamlines substation testing protocols by automating multi-terminal acquisition while adhering strictly to international diagnostic benchmarks.

Key Upgraded Functions of the MS-101 Series
As a premier Dielectric Analyzer, the MS-101 series incorporates eight major functional upgrades:
- Simultaneous C_1/C_2 Primary Wiring: Measures main insulation and tap insulation without resetting test leads.
- Transformer Ratio and Polarity Testing: Validates transformer vector grouping and turns ratio concurrently.
- Customizable Frequency Curves: Plots insulation response across frequencies from $40\text{Hz}$ to 70Hz.
Frequently Asked Questions (FAQ)
Q: What is the benefit of measuring C_1$ and C_2 simultaneously on transformer bushings?
A: Simultaneous measurement eliminates environmental variations between tests, ensuring that both main insulation (C_1) and tap insulation (C_2) are evaluated under identical thermal and voltage conditions, per IEEE Std C57.19.01.
Q: How does the wireless Bluetooth feature enhance field safety?
A: Operators can initiate tests and monitor real-time data backflow from a safe distance outside the high-voltage exclusion zone.
