The relay protection tester is a new generation of calibration device successfully developed on the basis of the original JBC. The internal AC and DC voltage and current sources of this instrument adopt the latest power technology, which provides convenience for field personnel to use power instrument technology for other tests. Under the premise of simplifying the operation, the instrument can increase the functions of the instrument, which can be used for various tests. The common relays carry out various checks and the panel layout is exquisite, allowing the operator to operate easily and clearly at a glance, thus welcoming the unanimous praise of the majority of users.

2. The instrument uses power supply AC220V±5%, 50Hz±5%
3. Function
The LDJB-702 relay protection tester can verify the following various relays or group protections:
(1) Measuring relays: including current and voltage type relays, which can measure their starting value, return value and their coefficients.
(2) Time relay: It can measure its start value, return value and its action time, and the time measurement error is not more than 0.2ms.
(3) Intermediate relays: the calibration of various intermediate relays with start coils and holding coils can measure the start value, return value, holding value and action time.
