Portable Relay Test Sets

We are committed to offering a quality range of Portable Relay Test Sets. These have built-in  micro controller based multi range time interval meter and have panel with clear and easy to read legends.

Features:

• Continuously adjustable output, AC Amp. and AC volts
• Digital ammeter and voltmeter
• Auto cut-off and output isolated
• Portable, suit-case model
• Self sensing of contacts, i. e. NO / NC
• Timer automatically puts OFF the output, when timer reaches to its maximum value of the selected range to ensure safety of the instrument as well as the item under test
• Potential-free start and stop signal
• Wide range of measurement, i. e. from I millisecond. to 9999 secs

Application:

The protective devices such as relays, overload coils, circuit breakers must be checked regularly to ensure that, they are always ready to operate correctly. If a fault occurs in the equipment, which they are protecting, routine relay testing will quickly detect the faulty, incorrectly adjusted protection circuit and will possibly prevent serious damage to plant or injury to personnel. Apart from checking the protective circuits correctly, it is usually necessary to measure its operating time. The micro controller based time interval meter is used for this purpose in all AJIT brand relay test sets.
