FAQ's of Electrical Knee Point Tester:

Q: How does the Electrical Knee Point Tester function in a substation environment?

A: The tester is primarily used to determine the knee point voltage of current transformers (CTs) in substations. Its digital LCD panel and precise voltage/current output enable accurate characterization of CT behavior, essential for reliable protection and metering.

Q: What applications is this knee point tester suitable for?

A: This instrument is ideal for electrical substations and laboratory settings, especially for testing current transformers to ensure performance standards. Its robust construction and compliance with IEC 61010-1 make it suitable for professional use across India.

Q: When should I utilize the data storage feature of the tester?

A: The internal memory, capable of saving up to 100 sets of test data, is beneficial when multiple tests are conducted in a single session or across multiple sites, allowing efficient data management and facilitating later analysis or reporting.

Q: Where can I operate this tester safely?

A: Designed for use in indoor substations and controlled laboratory environments, the tester is shock-resistant, dust-proof, and operates optimally between 0C and 40C, under standard atmospheric pressure.

Q: What process provides protection against overload or short circuit?

A: Integrated overload and short circuit protection systems immediately trigger an audio-visual alarm to alert users, helping prevent damage to both the instrument and the CT under test.

Q: How does the rechargeable lithium-ion battery improve the tester's usability?

A: The rechargeable battery offers flexibility for field engineers by permitting cordless operation, especially useful in locations where a 230V AC power source is unavailable or inconvenient.

Q: What benefits does using this knee point tester offer distributors and suppliers?

A: As a compact, accurate, and durable instrument, it caters to a broad professional market-including distributors, exporters, and laboratories-enhancing their portfolio of precision electrical testing solutions.
